One thing about the AS that has much in its favor (my thinking) is its shape. As I said in earlier post, when my husband picked up our Minuet - it had no sway control, no special tow pkg, no brake system - the trailer sat on its ball hitch with a couple chains attached, thats all. He had absolutely no problems thru Michigan, Illinois, Iowa, Nebraska and into Colorado. He even commented on it being Big Rig Country around Illinois (he had never seen so many on the road, back to back to back, etc). Not that I would allow him to leave it that way, and I would have been white knuckled on that trip.
As far as the "Lil Dragin", our moving trailer - the trooper said I hydroplaned on the water and that caused the trailer to start its sway. I'm sure its weight was unevenly distributed (we were young and clueless) and of course it wasn't a deluxe model!! Take some time to consider and get what makes you feel safest. Leigh
