I have been towing a TT bumper pull weigning in at 8,600 with a totally loaded vehicle weight of 17,000 on my 2018 2500 4X4 6.4 with 66 Rfe transmission, 33" tires, with 373 gear set. I have to look in the RV to see that the guy following so closely is actually my camper. I'm finding 65 mph give me 8.7 mpg over a 2,700 mile trip through mountains and plains. The current combo hits 11% grades in KY, PA, AR very smoothly at speed. I'm making a move to a 5th wheel and am targeting 2,275 hitch with a 11,400 dry + 2,000 lb cargo. So now I'm thinking of a move from 3,73's to 4.10's (factory option), and read that 4.56's might actually be more appropriate with the 35" tires. Does anyone have an opinion? Don't want the diesel for a variety of reasons. The truck is used primarily for tow with occasional casual use. Thanks
