That’s a good way to ruin an air bag, especially the one that is on the ground. Those ramps are the problem. Should be long enough to put both axles on them. I don’t know why ones on the ground and one isn’t. Maybe the anti walk if equipped on rear axle isn’t catching on one side. Set the brakes, and look at the back of rear axle. See if the arms are working, and not broken. If going there often, I think I’d bring a couple short 2x6 blocks for the front axles tired to sit on.
