What Did You Do For Your Travel Trailer Recently?

Between camping trips my camper is parked on the lawn beside my garage where the ground is not level. I had to drive the low side up on blocks every time I parked it. I solved this problem with four 2 foot square stepping stones. I place one at each tire and used fill to get them level. Now I just aim for the stepping stones and when alll four wheels hit the camper is level.
