CHASSIS manufacturers have announced guidelines and restrictions regarding removal of pickup boxes for the 2004 model year, according to a technical bulletin published by the National Truck Equipment Association.
By complying with the truck manufacturer's guidelines, distributors can remove the pickup box and install a commercial truck body without having to accept additional certification responsibilities for federal motor vehicle safety standards.
The following are the domestic pickups to which pickup-box removal programs apply.
Dodge will allow pickup-box removal, under prescribed conditions on these 2004 model vehicles:
Dodge will allow pickup boxes to be removed on 4×2 and 4×4 models. However, the manufacturer does not recommend removal of pickup boxes from models with dual rear wheels.
Qualifying vehicles cannot be converted for use with dump bodies, aerial devices, cranes, wreckers, ambulance bodies, motor homes, or recovery vehicles.
Ford is allowing pickup box removal on selected Ranger and F-Series trucks. Eligible Rangers are SuperCab models with GVW ratings of 4,600-5,260 pounds. The second-unit body must weigh at least 230 pounds, but it cannot exceed a maximum weight that varies by model.
The model line-up for Super Duty F-Series is as follows:
Chevrolet and GM will allow the pickup boxes to be removed on these trucks in 2004:

Some models can accommodate bodies that are more than 62 inches in overall height, but the CG cannot exceed 20.3 inches above the frame.
