pmclemore has good advice, a phone call to Andy T at CanAm will get you the advice you need. Personally I think you should be just fine provided you take some care with the set up (hitch, WD and payload) and use either friction anti-sway or better yet a ProPride or similar.
Andy's go-to hitch is the Eaz-Lift with 2 x friction sway control units. I ran with that configuration for a while with my 27FB based on his advice and was happy with it. I switched to a ProPride later - not because I felt the need to change but more because I had my heart set on a ProPride from the outset.
If you have an hour or two on your hands read this thread - http://www.airforums.com/forums/f463...rs-134917.html
. Lots of good info here. I think I posted some pictures of Andy T's setup of a 30ft AS there. If you have further questions, post on that thread.
