I just finished my DIY dolly build. I tried to duplicate the design of the Seitech Dollys at my club and used Unistrut channel which I was surprised I haven't seen anyone else make use of in other DIY builds. In total it cost me about $130 to make. I have a welder so I welded on the axles and the handle bar but it'd definitely be possible to come up with alternative attachment ideas for someone without access to a welder. I still need to fabricate a bow support bracket but then she'll be good to go.
My favorite part about it is that in a less than a minute I can break it down into pieces and throw it in the truck bed with the boat for transport since I don't have a trailer.
