Without occupants and other items loaded in the cab, the FAW actually lightened up with the camper loaded. adding the weight in the cab brought it back.
The CG of a dry camper is over the rear axle, but on a short bed short wheelbase truck, there is quite a lot hanging behind the rear axle. In the case of the AF811, the pantry, generator, dual batteries and dual 30# LPG tanks are all aft of the axle. Fresh tank was forward of the axle, gray tank was over the axle and black tank was aft of the axle. The sticker weight on the dry camper without LPG or batteries was around 2950 lbs and actual scaled around 3850 lbs when loaded.
Our heavy options were: Cab over full wall wardrobe, Dual pane windows, Air conditioning, Convection microwave, Dual group 29 batteries and Generator. The only weight saving we had was an oven delete so we had a storage cabinet under the stove top.
I know that once I went to 19.5" rims and tires, the weight could creep up 300 lbs between camper and truck until I cleaned things out. At that point, I cared less about the amount and where it was located. When I originally ran 18" wheels, I loaded the front truck axle over 5000 lbs by carrying more in the cab and in the cab over of the camper and the trailer was loaded rear heavy to keep the tongue weight down. I was able to maintain a 7200 lb RAW by packing that weight far forward in the truck and far rear in the trailer.
