So, I've been researching frames and can't find ideas or advice on working with continuous rocker? I have a 15' Wing raft with top/bottom rockered diminishing tubes. The center section is "flat" for a total of 52" before the tubes start traveling up in successive sections. I'm worried a 3/4 bay flat frame's entire weight pushing down on the rockered section(s), not evenly distributing weight. I'm thinking of a 2 bay that would fit within the 52" and then add a trailer frame(s)? There are obvious flaws with this idea. DRE has a nifty way of using fittings to clamp the trailer to the main frame. A custom rocker shaped welded frame seems a bit out of my reach. Thoughts? Has anyone built something that fits big silly rocker?
