Look up Stable Lift. People who have them seem to be very pleased with the system. I hope you are successful in getting dh to look at the camper dw and I have enjoyed ours very much over the years.
I will always remember coming home with my "new to me" GMC 2500. When I backed it up to my Hallmark popup I was convinced that what I was seeing simply couldn't be true. Camper was just too wide to fit the truck. It wasn't too difficult to modify the width of the camper. As I recall, I need to remove almost 4 inches. Hardest part was taking a power saw to the camper! Go slow and think it thru before you fire up the power tools!
