I used to have that same problem. It stopped doing it when I changed the way that I set up the coach. My procedure is now...
1. Park coach, leave engine running, with brake set.
2. Connect shore power.
2. Put slides out.
3. Sit back down in drivers seat and press the Auto (I think) button on HWH leveler controller.
4. Wait for the coach to level. After 30 seconds or so, put foot on brake pedal and release air brake. This usually allows the coach to "jump up" to right level.
5. Set air brake again, and release foot pedal
5. If the auto-level kicked off, repress the auto button.
What this process does is take the pressure off the tag brake as opposed to the air leveling system. Since I have done it this way, I have rarely if ever heard that thunk.
cheers,
