I'm not saying anything good or bad about Alpha Coaches as I've never owned one. I've read a lot here and on other threads about them so you can too!
A couple of minor things is that their rear lights are too low. I've seen some that have added additional lights above to be seen over the tow vehicle. Another thing that Alpha's don't have are flush fitting cargo doors. The Alpha's that I've seen have rounded edges and very 'compartmentalized' with framing around each door which is not a smooth look.
But, I would prefer a coach manufacturer that is still in business. There are so many other choices of coaches that are 10-12 yrs. old that ARE still in business with factory support/parts (Newmar, Monaco, Beaver, Safari, Holiday Rambler, Thor, Damon, Fleetwood, American Coach, Tiffin, Winnebago, Itasca, Coachman)....... I know some of these are from the same manufacturer but they are still supported even though they don't make that brand name.
Good luck on what ever you decide.
