Summerset Quest 42 vs TRL Pro 40 Grills: Which Is Right for You?

The Summerset Quest 42 and TRL Pro 40 are both premium built-in gas grills constructed for substantial outdoor kitchens, but they emphasize different strengths. The Quest 42 focuses on size, included accessories, refined lighting, and a complete out-of-the-box cooking package. The TRL Pro 40 focuses more heavily on burner power, independent heat zones, commercial-style construction, and performance-focused value.

The practical question is not simply which grill sits higher in Summerset’s lineup. It is whether you would benefit more from the Quest’s larger exterior format and extensive accessory package or the TRL Pro’s four high-output main burners and significantly greater total heat capacity.

Both grills use #304 stainless steel, eight-millimeter square cooking grates, ceramic briquette heat-management systems, interior lighting, an infrared rear burner, and a heavy-duty rotisserie system. The differences become clearer when you compare burner layout, ignition, included accessories, hood design, price position, and how each grill is likely to be used.

Specifications, prices, accessories, and warranty terms can change. Confirm the current product page and manufacturer installation manual before ordering or fabricating the island cutout.

The Core Difference: Complete Luxury Package vs Performance Value

The Quest 42 and TRL Pro 40 share several important fundamentals. Both use commercial-grade #304 stainless-steel construction, ceramic briquettes, heat-zone separators, eight-millimeter square cooking grates, interior lights, LED burner-status indicators, infrared rear burners, and heavy-duty rotisserie systems.

The difference is where each model directs the additional value.

The Quest 42 adds a larger exterior format, spring-assisted hood, waterfall front-panel lighting, dishwasher-safe removable drip tray, warming-rack storage, griddle plate, smoker box, rib rack, multi-position warming racks, and a fitted vinyl cover. It is designed to feel like a complete outdoor culinary station from the day it is installed.

The TRL Pro 40 directs more of its value toward the burner system. Four 20,000-BTU main burners create four independently controlled zones and 80,000 BTUs before the rear burner is counted. That is substantially more main-burner output than the Quest’s three-burner, 54,000-BTU arrangement.

This does not automatically mean the TRL Pro cooks every food better. Total BTUs do not measure heat distribution, efficiency, or technique. However, the additional burner and greater output give the TRL Pro a clear practical advantage for cooks who frequently divide the surface into several temperature zones, load the grill heavily, or want strong heat recovery after opening the hood.

Who Should Buy the Summerset Quest 42?

The Summerset Quest 42 is a strong fit if:

• ✔ You want the largest Quest format for a substantial outdoor kitchen.
• ✔ You value an included griddle plate, smoker box, rib rack, rotisserie kit, warming racks, and fitted cover.
• ✔ You prefer to receive a coordinated accessory package instead of buying several add-ons separately.
• ✔ The spring-assisted hood would make a larger grill easier for you to use.
• ✔ Waterfall front-panel lighting and refined nighttime presentation are important.
• ✔ You want three broad heat zones rather than four more narrowly divided burner zones.
• ✔ You entertain frequently and want several cooking methods available from one built-in grill.
• ✔ The higher price fits comfortably within the complete outdoor-kitchen budget.

The Quest 42 may not be your best choice if:

• You prioritize maximum heat output and independently controlled burner zones.
• You are unlikely to use the included griddle, smoker box, rib rack, or additional warming equipment.
• You want the strongest performance-per-dollar within these two choices.
• Your island does not comfortably accommodate its 42-inch body and installation requirements.
• You prefer a simpler package and plan to select accessories individually.

Who Should Buy the Summerset TRL Pro 40?

The Summerset TRL Pro 40 is a strong fit if:

• ✔ You want four independently controlled main burners.
• ✔ You value 80,000 BTUs from the main cooking system and 95,000 total published BTUs.
• ✔ You frequently cook several foods at different temperatures.
• ✔ You want strong preheating and recovery capacity for high-volume grilling.
• ✔ Battery-free flame-thrower ignition appeals to you.
• ✔ You want premium #304 stainless-steel construction without paying for a large accessory bundle.
• ✔ You already own—or prefer to select—your own griddle, smoker box, racks, and grill cover.
• ✔ You want the lower-priced option while retaining premium construction, lighting, briquettes, and rotisserie capability.

The TRL Pro 40 may not be your best choice if:

• You want the Quest’s more dramatic front-panel lighting.
• You prefer a spring-assisted hood.
• You want a coordinated accessory package included with the grill.
• The larger 42-inch Quest format better suits the visual proportions of your island.
• You value luxury presentation and included equipment more than maximum burner output.

Our Summerset Buying Recommendations

Best Complete Luxury Package: Summerset Quest 42

Best Performance and Value: Summerset TRL Pro 40

Which Grill Wins Each Category?

Which Is Better for Entertaining?

Both grills are capable of serving a group, and both list approximately 1,000 square inches of total cooking area including their warming racks. The better entertaining choice depends on how you host.

Choose the Quest 42 when entertaining means variety. Its included griddle, smoker box, rib rack, rotisserie kit, and adjustable warming equipment provide several ways to prepare and stage food without immediately purchasing more accessories.

Choose the TRL Pro 40 when entertaining means volume and simultaneous heat zones. Four high-output main burners make it easier to cook different foods at different temperatures and recover heat after the hood has been opened repeatedly.

For most hosts who primarily grill steaks, burgers, chicken, vegetables, and other direct-grilled foods, the TRL Pro may be the more functional choice. For hosts who enjoy varied cooking methods and want a complete accessory collection, the Quest may provide the more enjoyable package.

Which Is Better for High-Heat Cooking?

The TRL Pro 40 has the stronger published burner system. Its four main burners produce 80,000 BTUs, compared with 54,000 BTUs from the Quest’s three main burners.

That does not guarantee identical temperatures across every point of the grate, and BTUs alone should never determine the purchase. Grill construction, airflow, briquettes, cooking-grid mass, weather, preheating, and food load all affect performance.

Nevertheless, buyers who regularly cook at high temperatures, load the grill heavily, or want fast heat recovery have a clear reason to favor the TRL Pro.

For additional high-temperature options, see the Best Grills for High-Heat Searing guide.

Which Is Better for Smoking and Rotisserie Cooking?

Both grills include infrared rear burners and heavy-duty rotisserie systems, so neither has a decisive advantage for standard rotisserie cooking. The TRL Pro’s rear burner has slightly more published output, while the Quest includes more supporting accessories.

The Quest is the more complete package for experimenting with smoke because it includes a smoker box. However, neither grill replaces a dedicated smoker or ceramic kamado for someone whose primary goal is traditional low-and-slow barbecue.

Buy the Quest when you want occasional smoke flavor and the convenience of an included smoker box. Buy the TRL Pro when rotisserie cooking and main-grill performance matter more than receiving every accessory in the box.

Which Is Easier to Live With?

The Quest includes several ownership conveniences:

• Spring-assisted hood operation
• Dishwasher-safe removable drip tray
• Storage provision for warming racks
• Included fitted cover
• Several included cooking accessories

The TRL Pro takes a simpler approach. Its battery-free ignition, four-burner layout, briquette system, lighting, and conventional accessory package are straightforward. It may create less accessory storage and management for a buyer who prefers to purchase only what will actually be used.

The Quest is easier for someone who wants a complete package. The TRL Pro is easier for someone who prefers a more focused grill and fewer bundled components.

Installation Considerations

Both models are permanent built-in appliances that require careful coordination with the outdoor-kitchen contractor, gas professional, countertop fabricator, and any ventilation professional involved in the project.

Before ordering either grill, confirm:

• ✔ The exact current manufacturer cutout dimensions
• ✔ Natural-gas or liquid-propane configuration
• ✔ Gas-line capacity and regulator requirements
• ✔ High and low island ventilation openings
• ✔ Combustible and non-combustible clearance requirements
• ✔ Whether an insulating jacket is required
• ✔ Access for shutoff valves, ignition components, drip trays, and servicing
• ✔ Exhaust-hood requirements under covered structures
• ✔ Current local building, fire, gas, and electrical codes

Do not fabricate the countertop opening using the advertised grill width. A 42-inch grill does not use a 42-inch cutout, and a 40-inch grill does not use a 40-inch cutout. Build from the exact current installation manual for the specific fuel configuration.

For broader planning guidance, see the Best Grills for Outdoor Kitchens guide.

Natural Gas or Liquid Propane?

Both the Quest 42 and TRL Pro 40 are offered in natural-gas and liquid-propane configurations.

Choose natural gas when the home has an appropriately sized permanent supply line or when one can be professionally installed. It eliminates tank changes and is convenient for frequent grilling.

Choose liquid propane when natural gas is unavailable or when the outdoor-kitchen plan specifically calls for propane. The enclosure must provide suitable tank access, regulator placement, shutoff access, and ventilation.

Order the correct factory fuel configuration. Do not assume a conversion is automatically permitted, simple, or preferable to purchasing the correct model.

Is the Quest 42 Worth the Higher Price?

The Quest 42 can justify its higher price when the included package replaces equipment you would otherwise purchase separately. Its griddle plate, smoker box, rib rack, rotisserie kit, warming racks, fitted cover, waterfall lighting, and spring-assisted hood all contribute to the ownership experience.

It is more difficult to justify when the buyer mainly wants conventional gas grilling. The TRL Pro delivers an additional main burner, considerably more total output, similar published cooking area, the same grate thickness, similar briquette heat management, lighting, rotisserie capability, and the same broad warranty positioning.

A practical decision rule is:

1. Choose TRL Pro if the cooking system is the priority.
2. Choose Quest if the complete package is the priority.
3. Do not pay for included accessories unless you expect to use them.
4. Do not choose by BTUs alone if the Quest’s usability features matter more to you.

Final Buying Recommendation

• ✔ Choose the Summerset TRL Pro 40 for the strongest combination of burner output, four-zone flexibility, premium construction, and performance value.
• ✔ Choose the Summerset Quest 42 for the larger luxury format, spring-assisted hood, enhanced visual presentation, and extensive included accessory package.
• ✔ Choose TRL Pro if you expect most meals to involve conventional grilling, multi-zone cooking, and high-volume heat.
• ✔ Choose Quest if you expect to use the griddle, smoker box, rib rack, rotisserie, and warming accessories regularly.

For most performance-focused buyers, the TRL Pro 40 is the more compelling purchase. The Quest 42 is the better fit for someone who wants the most complete Summerset cooking package and values its added refinement enough to justify the premium.

Summerset Quest vs TRL Pro FAQ

Is the Summerset Quest better than the TRL Pro?

The Quest is better for buyers who want a larger format, spring-assisted hood, enhanced lighting, and an extensive accessory package. The TRL Pro is better for buyers who prioritize burner power, four independently controlled heat zones, and stronger performance value.

Which grill has more power?

The TRL Pro 40 has substantially more published output. Its four main burners produce 80,000 BTUs, and its rear burner adds 15,000 BTUs for 95,000 total. The Quest 42 lists 54,000 BTUs from its three main burners and 13,000 BTUs from its rear burner for 67,000 total.

Which grill has more cooking space?

Both product listings state approximately 1,000 square inches of cooking area when the warming rack is included. The Quest has the larger advertised exterior width, but the published total cooking-area figures are similar.

Why does the Quest cost more than the TRL Pro?

The Quest includes a broader luxury and accessory package: waterfall front-panel lighting, spring-assisted hood operation, griddle plate, smoker box, rib rack, rotisserie kit, multi-position warming racks, and fitted cover. Its premium is not based on having more burner output.

Which grill is better for entertaining?

The TRL Pro is better for cooking several foods at different temperatures because it has four main burners and higher output. The Quest is better for hosts who want several included cooking accessories and a more elaborate presentation.

Which grill is better for high-heat grilling?

The TRL Pro has the advantage based on its four 20,000-BTU main burners and higher total output. Actual grill temperature still depends on preheating, airflow, briquettes, weather, and how the cooking surface is loaded.

Which grill is better for rotisserie cooking?

Both are strong rotisserie options. Each includes an infrared rear burner and a heavy-duty rotisserie system with a 40-pound motor. The TRL Pro has slightly more published rear-burner output, while the Quest includes more supporting accessories.

Which grill is better for smoking?

The Quest includes a smoker box, making it easier to add occasional smoke flavor without buying another accessory. Neither is a direct replacement for a dedicated smoker or ceramic kamado when low-and-slow barbecue is the primary goal.

Does the Quest include more accessories?

Yes. The Quest package includes a griddle plate, smoker box, rib rack, rotisserie kit, multi-position warming racks, and vinyl cover. The TRL Pro’s primary included specialty accessory is its heavy-duty rotisserie system.

Do both grills use ceramic briquettes?

Yes. Both use easy-clean ceramic briquette systems intended to distribute radiant heat, shield the burners, vaporize drippings, and reduce direct flare exposure.

Are both grills made from 304 stainless steel?

The current listings describe both grills as using commercial-grade #304 stainless-steel construction, including their bodies and burners. Review the current product specifications for component-level material details before ordering.

Are the Quest and TRL Pro available in propane?

Yes. Both are offered in natural-gas and liquid-propane configurations. Select the correct fuel model when ordering and confirm all gas, regulator, ventilation, and installation requirements.

Do they have the same warranty?

Both are backed by Summerset’s Gold Standard limited lifetime warranty program. Coverage varies by component and generally applies to the original registered residential purchaser. Registration deadlines, labor exclusions, and current terms should be confirmed in the manufacturer warranty documentation.

Which grill is the better value?

The TRL Pro 40 is generally the stronger performance value because it offers four main burners, 95,000 total published BTUs, premium construction, lighting, briquettes, and rotisserie capability at the lower current price position. The Quest may be the better total-package value when its included accessories and premium convenience features would otherwise be purchased separately.

Should I buy the Quest 42 or TRL Pro 40?

Buy the Quest 42 if you want the full accessory package, larger luxury presence, spring-assisted hood, and upgraded lighting. Buy the TRL Pro 40 if you want the stronger burner system, four-zone flexibility, and the more performance-focused purchase.
