The Zenith Builder Forums are closed to anyone who is not building or currently owns a Zenith, and zenithowner.com does not appear to have much activity, so I am looking for alternatives.

I am considering the purchase of a Zenith 601HD, and I am looking for information, but I am having trouble finding answers to a couple questions.

1) What (if any) is the difference between a 1200lb gross 601 and a 1050lb gross 601?

2) Where can I find a good A&P with 601 experience near OK/AR for a prebuy?

Any suggestion on where to find this info?
