Great reviews on the Barneys, M1 and Kelly. I was scrolling on YouTube and found the Slumber Jack Rail Frame. Says it'll hold 200 lbs... Ain't no way in hell this hillbilly could haul 200lbs but it's a well thought out frame with load lifters.
Lots of frame choices out there with plenty of options.

Whatever I get, I've got to make sure it'll fit my 13 year old son comfortably laugh ... He's closing in on 6' tall and 180 lbs.
