First off why do they even put that little joke of a fan in our RVs? I know the answer
but they are pretty much useless. It's funny that this thread popped up because just yesterday the DW and Me were discussing changing it out and were looking at what options are available. I had put the Heng's Vortex II in the old 5ver's bathroom and was thinking about putting one in the Alpine. The problem is the DW while she is not that short can barely reach the vent opener and the switch on the existing fan because the ceiling is 7' high. So I am looking at ones with a remote. Getting back to the Heng's I liked that it had a variable speeds and a reverse, the noise wasn't that bad unless you ran it wide open.
