I am going to post updates and photos as I try to build a trailer for camping. Grinding away paint so we can weld the frame Safety first, then teamwork. Welding complete… paint the trailer black to give a bit of rust protection, and its more aesthetically pleasing A nice painted 4×8 trailer Mocking up how this might work with extending over the wheels. frame mockup part 2 Months later, I have a plywood floor done! Next step is to spray on some waterproofing material and bolt it down.
