It sounds as if the stabilizers may not be working correctly. They're not intended to level the coach, merely to keep it from rocking from side to side. I think a true leveling system would involve more money, more weight, and, perhaps, less ground clearance.
Anyway, my stabilizers seem to do a pretty good (not perfect) job of keeping motion to a minimum. Perhaps yours need to be adjusted? One thing you could do yourself is to follow the bigfoot instructions for bleeding the air out of the system. The bigfoot manual includes a troubleshooting section, which includes the following suggestions (among others):
- There may be air in the system… Fully extend both jacks leave for 30 minutes... Lower jacks.
- Low fluid level (Must be 3/4” below top of reservoir)
- To purge system, add necessary fluid and run up & down a few times.
You might try these (or some of the other troubleshooting ideas). If they don't work, you'll probably need to contact their customer support at (269) 483-9634 or firstname.lastname@example.org
