I am thinking that the old back could use a bit of relief from lifting my canoes around. I now have a 17' Chestnut, and I just finished rebuilding a OT 15' square stern. I keep these behind my garage under a patio cover. I have a couple of trailers (one for white water rafting and a nice little Monkey Wards unit) but I don't keep boats on them. I also have 2 9' sailing dinghies that weigh over 100 lbs that I use with the Scouts for Small Boat Sailing MB work. I have been looking at the InSTEP aluminum CC450 ($54 on ebay) and the CC100 steel unit ($62-74 on ebay). I'll bet that other have experience with these, or others, and can provide a recommendation for the best unit for utility and price. Cabella's has these on their site with some good reviews. I think the Aluminum one looks pretty functional. Any input to confuse me further is greatly appreciated.
