In our old camper, there are 3 handles under a cup holder on top of the dash which operate the basic valve system. You can hear the air sucking up or blowing out (even without a hearing aid). When you raise the camper to MAX position then drive it a bit, it levels itself out. That's about the only automatic feature on the old gal...except for the diesel fills, that's an auto function if you want to drive it. Fills on both sides. When we're in Florida will try to post some pictures of a few things for nostalgia purposes if anyone's interested...assuming, well, y'know.
