A Chassis Cab truck is a heavy-duty vehicle sold without a rear body so fleet operators and tradespeople can mount custom upfits like flatbeds, service bodies, or dump configurations directly to the frame. RAM offers this platform in 3500, 4500, and 5500 configurations with GVWR ratings spanning Class 3 through Class 5.
The right Chassis Cab class depends on the weight of the upfit body, required payload rating, and whether dual rear wheels are needed for load stability. Max trailer weight and max tongue weight increase across the 3500, 4500, and 5500, so the job dictates the class.
Cab type determines the available frame length behind the cab, which sets the maximum upfit body size that can be mounted. Regular cab configurations give upfitters more rear frame to work with than crew cab models.
