Began the frame this week. got the main runners and the tongue cut and fit. Going to weld it all up hopefully this weekend. Then I can cut and fit the side extensions to bring it out to 60 inches wide. The tires will be tucked up under the body for a little more then half their width.
Frame layed out: This is 47 inches wide and 8 feet long for the main box. The tongue adds about 4 feet to the overall length.

It does not look like it but there is an inch of clearance between the frame and the tire sidewall.

Tongue detail. There will be supports for the tongue to frame joint to keep it from breaking.

The tongue, main frame runners and joint support piece are 2x2x3/16" steel. The cross members and rest of the frame are 2x2x1/8"
The hitch coupler is from Lock-N-Roll. It is designed for off-road use.
