For some unkown reason, the camper certification weight is usually significantly less than actual payload capacity of the truck. It makes very little sense, but it is very common and has been for years.

Possibly they're accounting for the higher vertical center of gravity, and increased frontal area (height and width) of a truck camper load, versus a load of rocks, etc, of the same weight....

I think much of it has to do with where the axle is placed in relation to the bed space. In other words, in some trucks, namely crew cab trucks with shorter beds, it may be impossible to load the bed to the truck's max payload without overloading the rear axle. A slide in camper compounds this problem if the camper is longer than the truck bed since it will transfer weight off the front axle onto the rear.

Simple, max camper wt is the total payload, less # of seats fill at 150 lbs per person. So if you have a crew cab that will seat 6 people, 3000 lb TOTAL payload sticker on the door. Camper load is 2100. ALL of my trucks with pickup boxes have had this comparison since the early mid 90's or there abouts.

Even the FIRST new truck I bought in 81, the camper load sticker was the total payload, less 450 lbs in that trucks case to get the camper load. But the one thing that truck did not have vs todays truck, is the door sticker with the total payload on it. You had to do that the hard way, weigh the truck, take away from gvwr to get payload empty, then subtract 450, and you were usually with in 100 lbs of net wt.
