Definitely don't want to start my truck is better than your truck post. Beginning to look at 2022/2023 dually F350 or F450 and the GM 3500. Long box, 4x4, diesels in Lariat or King Ranch and High ...
I agree with the only you can determine that. While a larger tank is nice, I know I'll want to get out and walk every 2-3 hours, so with an HD (Diesel I'm guessing), I can always do that at a truck stop if I need. Having had all 3 brands recently, I found the Ram sits the best for me. The new Chevy (only tried custom 1/2 ton), seats were too narrow and my F-150 were a little too long. But as others also said different trims will have different seats.
