I have a forty foot motorhome that is our first. I had a problem on our last trip breaking camp. Getting ready to go I raised all four jacks but the front left was fully retracted but sitting on the block I used due to having a low corner on our site. Once I set the block down under the jack when setting up, there was one and one quarter inch of space between the pad and wood block. When getting ready to leave I raised the jacks and started the engine to fill the airbags but the coach remained on top of the block. What happened to the one and one quarter inch space I had? We had to dig and chip away at gravel to get the block out. Is there something I am doing incorrectlyY. Thanks for any help.

Did the motorhome raise at the other corners when the air suspension was up to pressure?

You couldn’t raise it back up with the jack and put a couple boards or something under the nearest tire?

What happened? You loaded all your "Travel stuff" and thus loaded it down.. likely about 1.5" This is easier with a car... Measure the bumper height with the car basically empty. Do this at the rear bumper.. Now open the trunk and set 3 or 4 5 gallon pails of water inside (however many you can fit) and measure the bumper height again.. Now remove the buckets .. carefully (you might put only 4 gallons in)Each gallon is what about 8.6 pounds so 4 times 4 gallons is a bit over 250 pounds.. Now imagine all the stuff you put in the RV.

You may have an intermittently failing leveling valve on that corner (for your air bags). If that is the case, obviously you'd want to get it replaced to resolve the issue. But, in the meantime, dumping air using your jack controller might correct the issue by moving the leveler through some of its stroke, thus getting it to allow air back into the air bag and raise that corner of the coach back up.

And even moreso how the camper got that much heavier “after” a comping trip where the same stuff goes home minus the heavy consumables.But moreso I’m trying to imagine how even a wacky theory like that applies to air ride….
