Gonna attach the 3" PVC tonight with some rubber grommets, washers and screws.
John Boat trailer from craigslist = $250
Bigger wheels from Northern Freight = $80 (they are half off right now BTW)
2x4 and PVC = $25
Still thinking about removing the wench up front so I can move the yak up a little. I think the yak will end up sitting to high but I've gone this far...
I might end up taking it to a welding shop after a while depending on how this goes.
