I built the frame 6'x6'6" myself from 2"x3" .065 wall steel for keeping the trailer light. All of the square tubing is 1/16" thick 1"x1" square tubing. The frame and structure will be welded then the interior will be installed. I am hand building all of the doors and windows will be installed. A vent with a three speed reversible fan will be on the top with a solar panel. This has a 3500 lb axle that I shortened and installed a 4" lift Jeep leaf spring over. I also mad all of the mounts.
So far I have about 6 actual hours on the build.
Feel free to ask any questions. I do have to finish this project by the end of May for the Ventura Off Road Show.
Molon Labe..... Look it up!
