I just purchased a 31BHS, I hope I made the right choice. There were so many to look at. I got a great price, The dealer was good also. I have gone through it pretty good. But until you have been inside and spent some time in it you just dont get to see all the little things. So far the only thing I have found is a screw coming up under the linolium. I took the vent off and slipped a piece of brazing rod in but it didnt move. I was hoping it wouldve been a small pebble or something. I will have to bring it back before I get a hole in the flooring.
