You don't need more rear end than that for 7500#. I have a chevy but just bought an F250. They all come w/ 3:31. It pulls 14,000 lb w/ no problem. I was surprised at the ratio. I figured theLooking at a 2022 Silverado 3500 HD dual rear wheel and the only thing I'm hesitant on is the 3.42 rear axel. I will be towing my bumper pull 32' toy hauler (7,500 dry weight) and will be purchasing a new goose neck three horse trailer with living quarters in the near future (30-35 feet). Live in the flat part of Ohio but not wanting to limit myself with a crap rear axel. Should I keep looking or will the 3:42 rear end work?
standard would be 3:73 but no. BTW The Ford Cab & Chassis come w/ variety up to 4:10, 4:30. & 4:88. You wouldn't want to buy the fuel for those. My Ford gets 4 mpg better than chevy on the road-real mpg, not fantasy
