We have had a camper for over a year now and the one thing my wife complains about it the camper not being level. I've looked at the plastic blocks you back the camper onto... nah! Installed a California portable air compressor in the camper for my trucks air bags and that got me looking for a portable air bags for the camper, looked at several and they cost way to much. Found these air bags watching a video and it looked like it would work and the price was right.When I received the air bag, everything looked good in the box, looked like the addressed some of the issues I saw in the reviews, bolts looked upgraded, had two air diffrent air couplers and was put together very easily!Works great, lifts both sides of the camper with no issues, did have to put a block of wood in to get a little higher, but, that's not an issue. Plan to leave the portable air bag inflated under the camper while camping.Only thing I would say, is a little heavy, would not expect my wife to carry it, but, that was expected.
