Im looking at different ways of hauling a 13' Ocean kayak. I was wondering why you couldnt build a support system under the belly of a 5th wheel and mount it between the tires and the front of the camper. I could screw into the frame system of the trailer and build a support sysytem that the kayak could slide into. once in place use tie downs hooked to eyebolts in the frame and tighten up untill the kayak is nice and tight up against the bottom of the trailer. I only have one kayak at the moment but i see no reason why two kayaks wouldn't fit side by side. If anyone has seen this done or know why it couldnt be done please let me know. My tailer is the Outback sydney edition 36ft fifth wheel.
