We saw the ones at Camping World when in the Elkhart area the past couple of weeks. They had two motors, one on each side. It says they can be used to level as well as stabilizing. However, the price shown was $629. Installation was another $169, I think. I know the one Dale has can be lowered and raised manually as well as electrically. I'm not sure about the ones at CW.
Dale, maybe you'd like to give us a set and we'll tell everyone about it???
Aw, well, give me credit for trying.
