I highly recommend Kelly Tussing over at RVWholesalers. I've never checked on A-Frames, so I'm not sure if they even carry them, but I'd definitely recommend giving him a call on it. I just negotiated the third camper we've bought from him(us, in-laws, and my now one for my mother) and we've had great luck and excellent service every time. Can't recommend them enough. The owner, David Durnell (think I got that right) frequents the forums and is usually available for assistance if needed.
