Maybe some others understand, but I absolutely none of your comments make any sense to me.
I got a camper loading guide with my Dodge Ram. The guide is very simple. It shows what we know to be the case. The center of gravity of the camper needs to be forward of the rear axle. I also have a COG diagram for my Northstar camper. The diagram shows the expected location of COG for the wet camper without added cargo. Obviously adding cargo can move the COG. Ideally I load heavy items as low and as far forward as possible.
A COG behind the rear axle is never a good thing. A small difference might not mean much but as the COG moves back, steering and handling can be affected. In addition there is already an issue with the weight on the rear axle and transferring additional weight from the front to the rear axle is not desirable. This is true for loading all trucks whether the load is from a camper or just cargo in the truck bed. It would be analogous to loading a trailer with a negative tongue weight.
