Hello, Just looking for some thoughts on pulling hills with 3.42 gears. I'm going back to a pop-up TC @ 1800 lbs dry weight. The trucks I'm looking at are the Chevy and GMC 3500's SRW 4x4...
My new to me camper has an advertised UVW of 1675 lbs which when loaded translated to 2800 lbs at the scale. I also pull a 14000 lb 5er. Neither bothered my 2018 at all. My door sticker says 3470lbs, so much less than the ones you are looking at. Towed in the mountains all over North America and of course my 6 speed downshifted of the steepest grades, but was never stressed. The 10 speed should carry/tow like a champ.
