I have a 5x12 open trailer. The floor is wood and a couple of the planks are starting to rot. The previous owner only painted the topside of the wood and left it outside 24/7. I am gearing up for the coming year and want to start fresh and replace all the wood and paint both sides etc. One problem...the metal frame is boxed in, front and rear, around the wood. I am not a welder so I can either fab something with bolts and cut the welds on the rear or I was thinking I could pull the planks out, as is, and cut 45's in the new planks and re-mount them in the frame. 45's together, on top of each other, on top of a cross member towards the rear(less weight) and screw them together. I also considered cutting the welds on the rear, putting the new planks in, and taking it to a trailer shop and have them re-weld the rear frame that I cut. Any ideas or opinions would be great! Thanks!!
