My Chevy 2500HD 4x4 diesel weighs about 7,700 lbs. with me and a half tank of diesel. With my moderately loaded NL 8'11" Q Classic on the truck, the total Cat scale weight is 11,220 lbs....4,600 on the front axle, 6,620 on the rear axle. The truck MGVW rating is 10,000 lbs. with a 6,000 front axle incl in the plow package. I think the rear axle is rated at 6,200 lbs., although, American Axle Co. rates that axle somewhat higher. I have Michelin tires rated at 3,520 lbs. each, Roadmaster Active suspension and Rancho 9,000 shocks. It works well, but I try to keep the camper weight down as much as I can.
When the NL Camper was new with only full propane and no water or gear, the Cat weight was 4,420 front axle and 6,400 rear axle.
