My first trailer. No carpentry skills or tools other than a 7 inch saw and a square.
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.
