Thanks for the tip on the antenna! I never thought about it much, but it makes sense. I'm not too fond of the white wheels either, but I put a good coat of wax on them each year and so far, no rust.
Question to you, since you have experience with the antenna. The literature I got with the trailer says I need to lubricate the antenna O-rings twice a year to prevent it from leaking in through the shaft. So far, I don't see how to do that. Have you been able to do that on past trailers?
As far as the AR-ONE forum goes, it is pretty dead. Never any activity. Once you post something, you have to wait hours before you post anything else. This is a much better forum, though not dedicated to the AR-ONE.
