Well....... Lot's of negative comments, but IMHO, all is not lost. If you find a 10 year old Alpha that does not have problems, you are probably pretty safe in grabbing it. The most important advice I would give is to have the coach THOROUGHLY inspected by a qualified RV tech first, making sure to point out the concerns noted in this thread.
There are a couple of Alpha's that frequent the CG where we stay. They look to be in good shape and the owners love them. So, I wouldn't simply discount getting one. You'll probably get a GREAT deal on one, if you perform your due diligence.......
