Air Suspension ?
I have air susp on my 97 eddie bauer exped. and it seems to be getting less tolerant to staying at a constant level. If I turn it off then I get the check suspension warning. I can go inside for a few mins and when I return the rear of the truck will be completely down. Once I start her up, she comes right back to the correct level. When I first got the truck it rarely went down at all. Should I be concerned about this.
