Ahhh yes....looking for a way out of the freebie "vibrating bed" addition to your coach are you?
The tripod probably will not help - we had similar issues with our coach (and we have a 4 point auto-leveling system). We had vibration as well!
A couple of things to check: Believe it or not, it is a common gaff for the techs to leave the shipping bolts in the washer! This was not our case, but something you may want to check - even though your unit is a couple years old.
Have a tech take a look and make sure your unit is not out of balance - in load balance - but make sure the drum is in balance and that all the counterweights are functioning properly. This was the BIG issue with our (new) Whirlpool.
Finally, when the washer is reinstalled in your unit, have the techs put in isolation dampeners (essentially they are big heavy-duty rubber washers) and a splash pan underneath the washer.
The dampeners will greatly mitigate the vibrations, since your washer is not now directly attached to the frame of your unit. The difference is amazing!
