It has been about a month since I posted in this thread, inquiring about the fuel tank size. In that span I've test driven four 4x4 trucks: '18 Tundra CC short bed 5.7 Platinum, '18 Ford F150 CC short bed 3.5 Lariat, '19 Ram 1500 CC short bed 5.7 Limited, and '19 Chevrolet 1500 CC short bed 6.2 LTZ. Fuel tank sizes were 38, 36, 33 and 24, respectively. Toyota was least quick, not particularly fun to drive, and cheesy inside. Ford was very fast, best visibility, harsh ride, noisy and dull interior. Ram was responsive, nimble on-road, plush ride, quiet inside and well appointed. Chevy was rocket strong, comfortable, easy to drive, second best ride, and surprisingly nice inside. To GM: you lost this sale due to having the smallest fuel tank. I've been planning to place an order on Monday, 10/15/18 for some time... and tomorrow Ram gets that order. With that written, I will say I like the new Chevy truck a lot. I've owned Dodge Ramcharger, Ford F350, and Nissan Titan in the past. So I have some clear ideas about what is important to me. Going in, I had Tundra, F150, Silverado then Ram in order as my favorites. Going out, its Silverado and Ram, tied for best, with Ford distant third, and Toyota last. As GM provides no on-line configuration tool for their product, and is otherwise silent on whether the there will be an increased tank size option, they made the decision pretty easy for me.

Good point... why not reduce down to 18 or 20 gallons, to really improve that MPG?

Yeah its puzzling. Why design a class leading truck then take a step backward with fuel tank size? The Colorado has a 21 gallon capacity... and the Silverado is only +3 over that?

After more homework, and to DougFL's point, seems like there is no increased capacity available. For example, in GM's own press release, linked here. Seems pretty clear cut. Definitely a head scratcher... guess only time will tell if sales are impacted.

This is the competitor's description of their max trailer package (below). Wouldn't it make sense, despite what the owner's manuals indicates, that the GM equivalent would also upgrade the fuel tank size? Includes: • 3.55 Electronic-locking rear-axle • 4-pin/7-pin wiring harness • 36 Gallon fuel tank • Auxiliary transmission oil cooler • Engine oil cooler • Class IV trailer hitch receiver • Pro Trailer Backup Assist with Tailgate LED • Smart Trailer Tow Connector (standard on LARIAT and higher) • Integrated Trailer Brake Controller • Upgraded front stabilizer bar • Upgraded rear bumper Requires 3.5L EcoBoost® engine. Does not include Trailer Tow Mirrors. Trailer Tow Mirrors are a standalone option and must be ordered separately. Max GCWR/Max Tow achieved on SuperCrew® when equipped with 20-inch Wheels. This configuration will also come equipped with max springs, steering gear, and upgraded stabilizer bar.

Interesting... so do you think that means, the package may include a larger fuel tank?

Thank you for this information. I was wondering if an option such as, "max trailering," would include a larger capacity fuel tank? From GMC's configurator, the, "details," revealed by max trailering package (shown below), doesn't list a larger fuel tank. Obviously the truck is brand new and one would suspect GM would eventually offer a larger tank, or is that thinking misguided? Increased towing and GCWR rating Automatic locking rear differential Handling/Trailering1 Suspension Package Enhanced cooling radiator Revised shock tuning Heavier duty rear springs and increased RGAWR 9.76" rear axle 3.42 axle ratio Trailer brake controller Trailering Equipment May require additional optional equipment

Prospective buyer here. Can anyone confirm the max possible fuel tank size?
