Here's mome pics of mine. It's made out of a 16' boat trailer. The rack is made out of galvanized pipe & pool noodles for padding. It will easily haul 4 kayaks (on their sides)on the rack & I have put 2 smaller yaks in the bed. Since the pics were taken I added ratchet type straps in the front & rear to cut down on swaying in case of a panic stop. It is bolted to the trailer bed with 16 bolts that take about 10 min to remove and then lift out the rack to use as a utility trailer.
