Elddis Chassis & Running Gear

You can level the campervan side-to-side using either a leveller jack or a ramp, checking with a spirit level across the floor. Using a leveller jack: lay it down ahead of whichever wheel needs lifting, drive up onto it, and wind the jack up until your spirit level reads level. Using a ramp instead: back up a little further than seems necessary, set the ramp down ahead of the wheel to raise, hold your spirit level running alongside the axle (or, failing that, just inside the door), then ease forward until the bubble settles centrally, and apply the handbrake, chocking the wheel too if needed.
