Seeing this late but comments are correct that this is an age old issue and probably the most debated one in the truck camper world.
I learned this the hard way and bought the current camper we have, a Northern Lite 8.11 SE, after I already had a near new Ford F250. My lack of knowledge at the time cost me about $6000 dollars when I made the decision to trade in my F250 with less than 10,000 miles on it for an F350 that had the payload capacity to handle our camper. Lesson learned but I am under all my published weight limits fully wet and can go down the road with confidence and sleep well at night knowing my rig is safe.
