Carol, yes DW wants to get one. And I just dont like cutting a hole in the side of our camper. I have done lots of searching on the 7100, but there are not many reviews on them. The 2 or 3 that I have found, folks are very happy with it.
Where did you order yours from?
Be sure to get the drain pan too:
