I agree with other's about the power issue. We bought an earlier version for our last camper (which we only used for two weeks... ugh). If we lost power to the camper, that was it. I did get a super-duper pillow top for it that helped though!
@West-Tex : I should add, we had an earlier version than the one in the camper, which was queen size, but not adjustable. It didn't work at all.
For adjustable beds, in my home bedroom, I have purchased Tempur Pedic beds. The latest one (since I lost DH), is a full size, with all the bells and whistles. I love it. (plus the light under the bed is pretty awesome!)
