I'll say not enough info to advise. I understand basically what is happening, but the why could be many reasons.
If everything is fine and to your liking when loaded up and headed down the road and the problem really is just a really bad dip or break over angle in your driveway that is worse than to be expected anywhere else, then some boards, airbags, higher hitch, etc should be the answer.
BTW, how much c rap are you putting in the back of the truck after you have the camper loaded?
Are you one of those, Traeger, 4 bikes, load of firewood, 5k generator, pop up tent, swingset for the kids, 200qt cooler with 3 racks of 'Stones on ice and a dog crate for your wolfhound kind of guy?
