So we bought our 98 K3500 crew cab 454 dually to haul a camper. We ended getting a relatively small camper (25 ft, 4500 lbs empty). Just my luck someone swapped the 4.10 gears for 4.56 gears. Obviously overkill and poor mpg/high cruising rpm has limited its use to just hauling. I have finally decided to change gears. I am contemplating 3.73 gears instead of 4.10s. If it had 4.10s, I would leave it alone but since I need to change anyway, that’s why I am considering 3.73. Factory tow rating is 12k, 10k and 8k respectively based on gears. Truck has stock size tires, runs well and is in good mechanical shape. Anyone have my truck with 3.73s? Most I am sure have 4.10s. Even if I had to tow in drive with 3.73s in the hills, I think it may make the truck overall more user friendly. Thanks.
