Oddly enough, I had the trailer built with reciever tubes on all 4 corners. I kinda thought about going off of those, but I think I'd need some triangulation in order to stiffen things up and not have a wobbly mess.
Even bad ideas. If for nothing else, they might spark another idea.
Kinda what I'm thinking is there's a vertical part that stands vertically front and back. If i bolt a ln 8020 extrusion to that, I can make a sliding section that goes up with a brake to hold it up.
I'm not sure I've got the room to get the travel I need. I'll have to clamp some blocks of wood down, make some marks to see if I can get what I want it off it or not.
Then it's a $500 gamble on material whether or not it'll work.
