I was able to locate one on craiglist and got it for short $. I really like it and am able to use it as a launching dolly, it is so light. Mine is an older unit and lacks the decal the newer ones have that advises you to run the tires at 15 P.S.I. . There are no springs on a trailex , only a rubber suspension pad between the axle and the trailer frame that provides road shock absorption. Running the tires at low PSI gives you additional road shock absorption and less jarring to your canoe. I have not noticed abnormal tire tread wear from running them low pressure. I tow the unit mostly with my pickup with an 8' bed. After launching, using the trailex as a dolly, I just singlehandledly lift the trailex (it is that light) into the bed of the truck and then easily park the truck in the tight parking spaces normally found at the locations where I paddle. I have hauled canoes ranging in length from 15' to 18'. On occasion, when I know I will be traversing ultra bumpy roads, I put the trailer into the truck bed , secure the hitch end into a front corner of the bed, and the axle at the end of the bed where the tires are on the dropped tailgate, load the canoe on the trailer and secure it as you would trailering it. A red flag on the sticking out end (required if there is more than 4' extending beyond the vehicle) is necessary with long canoes but the canoe is riding so high there is no chance of a vehicle hitting it. Works slick!! I think they are a great unit and am looking for another one. It serves as an easy storage unit also, just roll it into the garage by hand.
