You also need to consider what length is safe to haul. Have seen this formula for length, pretty sure there's some science behind it but wasn't quoted: "Rule of thumb (20’ for 110” wheelbase + 1’ for each additional 4” of wheelbase)" That was adopted (plagiarized) from a veteran RVer on this forum. With this formula, my previous GMC 1500 was right at the safe limit of (27.9' calculated) and my RV is 28' hitch to bumper. For what it's worth.
I sometimes see that rule of thumb using 113 inches for the beginning wheelbase. I also see a rule of thumb that the distance from the ball coupler to the centerline of the rear most axle should not be more than twice? the tow vehicle wheelbase.
