Hello Martin, I have a 2017 13'
Scamp and totally agree that you have to increase the ground clearance to avoid expensive repairs. I have replaced the toilet and drain line, grey water tank, and front jack. I just added 3" spacers using 2"x 3" tubing. A spacer or lift kit is the cheapest way to increase the camper height.
This will explain what I did

Etrailer may carry a riser that will work depending on which brand of
axle you have. I have a Lippert 2200 lb Axle and I think their part # LC270682 may work, check with them. They also have Lift Kits for Dexter Axles.
