Gee, I thought I was the only one that ever forgot to move the lever from the "Dump" position when traveling.
I did it once when leaving Myrtle Beach and drove for about thirty miles before I realized it.
Like you nothing happened and it didn't damage the air suspension bags.
Now I always shift the lever right away after dumping the air and leveling with the jacks. That way it is ready when I fire it up to air up the bags. Haven't ever did it again, thank goodness, might not be as lucky the next time and pinch one of the air bags.
