I picked up the ugliest damn trailer I have seen in awhile the other day. That said, after I finish with it, it won't be such an eyesore. The price was right @ $200.
I sold my 3 rail bike trailer to buy it. This covered one is home built and has odd measurements, but will transport a bike and gear easy enough. It is 7 ft long, 3'2" wide and around 4' 2" tall inside. I have to admit it looks pretty funny with those dimensions, but it tows very easy.
The frame, walls and roof are metal, and it has plywood flooring. If I can find someone who has some left over diamond plate - at a reasonable price - I'll lay some of that down inside.
I am sanding it down and treating the rust spots now and will paint later. After that I have to rewire it. God I am glad I like projects!
