Air Lift?

[Retired and Happy]

My motorhome is normally parked in my driveway which slopes down away from the street. I have built a couple of concrete ramps at the end of the drive to raise the front end and keep the thing level between trips.

After a couple months of non-use, when I got ready to leave for Spring Break a couple weeks ago, I noticed the bottom of the trailer ball was touching the pavement which I don't remember being normal. As I backed off the ramps, the rear end came up so I was able to get out of the drive without dragging.

When I returned home after a week, the bottom of the ball was about six inches above the concrete. Now that I've been home a few days, it seems to be sagging back down, maybe three inches above the concrete today.

Is this normal, or is there likely some sort of leak that bleeds off air pressure over time. I have an air indicator (a light?)on the dash, but I've never seen it do anything. And if pressure is bleeding off when not driven, would it build back up when driven?
