Hello all, I have a 2007 Fleetwood with the preinstalled track system. I want to put a canoe on top of my trailer using the four foam blocks that support the canoe on the roof of the trailer. All I want to do is find a way to slide some sort of an anchor into the Fleetwood track at four points to anchor hooks from two ratchet straps to in order to snug the canoe down to my roof. Anyone done this or have any ideas of how to go about it. Called an online rack store they said they don't have what I'm looking for. Any out of the box ideas would be great. Thanks.
