I got this trailer a few months ago in trade. It measures 10ft x4ft at the back, and shortens down to 10ft x 3ft 3ins at the front. The previous owner used it for kayaks. I used it as is for a while and hauled a good bit of wood with it, but its time to beef it up a little. You can see in the pictures that the sides are just 1x12s held on with metal L-brackets. Its not as flimsy as you may think, but I wanted something a little stronger. The weakest point is the tailgate, I plan to have a fully removable one in the finished version that will allow me to roll large rounds right into the back. Overall, its been working, but is just not solid enough for continued use. Here it is, mostly the same as when I got it: The plan is to completely disassemble the decking and wooden frame down to the metal frame. The metal frame, along with the fenders will get cleaned and coated in this rubber undercoating: http://www.harborfreight.com/rustoleum-12-oz-rubberized-undercoating-spray-67948.html The wooden frame and decking is still good, so that lumber will be re-used. I will re-assemble it with the only change being a wider front so that the trailer is uniformly 10x4 throughout. I ordered stake pockets and these corner stakeside connectors online: http://www.easternmarine.com/corner-stake-rack-connector-set-6020. All stakesides other than the front will be fully removable.The plan is to us 2x4 supports, and build the sides out of 2 2x6s each. The total height will be about 18 inches or so. I may add another 2x6 per side depending on cost. This trailer will be used for firewood as well as for my landscaping/handyman jobs, so I may extend the two middle supports on one side high enough to serve as a ladder rack. The stake pockets and connectors are supposed to be here today, so hopefully I can start working on it this weekend! Just thought Id start a thread with my basic plans and see if you guys had any input. Thanks!
