1988 G20 rear suspension question

[Campy]

Hi All, first time forum user, looking to find information on suspension upgrades and or suggestions for 1988 Chevy G 20 Okanagan version camper van. The rear seams to sit lower than the front when viewed from the side and not yet filled with supplies. I had the front end checked out and they say no issues there but steering is a little lazy.
Cheers

Your rear springs over time will weaken and allow the rear of camper to drop lower. You may also have problems with the air helper system.
