I started with a Northern aluminum trailer 40x48. and extended to floor to 6 feet. 8 inches over the front and the rest in the rear.

Built the frame.


I cut the sides and moved the axle back.

I didn't cut everything any where close to the same so I used small brackets to hold everything in place. I got like 30 of them holding everything.

I put some CPFC on the sides and top. And while I'm waiting to dry I will be doing the insides with electrical wiring and the walls will be just a drop cloth stapled to the frame.
I have installed a swivel and waiting on an MCHITCH for my Harley
Currently It looks like it will weigh about 425 to 450lb.
