OK see it that helps, PLEASE LET ME KNOW..... Thanks
I wounder if you could clarify how the corners work with your method. It looks like the welds are only on the inside of the tube leaving unsupported sheet extending across the face of the tube and terminating at the corner where you grind it flush. You mentioned JB weld used as a filler. Is it applied after the corners are ground? Did you use it along the entire length of each corner to connect the adjacent edges or just in spots? How much did you use?
might have missed it, but havent seen it yet...
the weight... what did you come up with for the trailer?
Empty & loaded with gear?
I just wonder if its worth it to consider doing it in Aluminum (sure thing to consider cost), but overall weight vs fuel costs may be not such a bad idea.
