My first travel trailer experience was with a Sylvansport Go that I purchased second hand. While I liked the look and the size of it, the put up and take down was horrendous and after every trip I swore that I was going to sell it. Well, I finally did last summer and my plan to replace it was to build my own trailer and minimize the effort required to set it up and take it down.
I like to paddle and spend time outdoors with my wife and three kids, so my plan was to make a trailer that was about the same height as a teardrop, but slightly larger and have a more conventional trailer shape. Along with running boards on each side, this will allow me to put the canoe, kayaks, and bikes on top.
I am starting with a 77”x12' aluminum trailer and all of the structure will be welded aluminum square tube. The top will be 1/8” diamond plate, and the sides will be charcoal gray painted aluminum. Front to back, there will be two 1 gallon propane tanks in front of the tongue box which will house the batteries and all of the electronics. Next, inside the trailer will be a sleeping area with roughly a king size bed, with storage above the head area. Slightly above and offset to the rear will be a twin bed, sideways across the trailer. This will be in two parts and removable. The offset portion of the bed will be above the 46 gallon water tank. Behind this will be a roughly 16-18” storage space where the water pump, pop-up shower room, generator, A/C, chairs, and all other items will go. Behind this will be the galley, which will consist of a refrigerator, compact dishwasher, pull-out two-burner stove, sink, propane hot water heater, and storage.
The area that I am really struggling with is the rear hatch. The rear of my trailer will look similar to the galley on 91kuhndog's trailer. However, instead of a pull-up or left/right doors, I really want to make a two-piece door, one above the other, that can be completely removed and used as tables behind the trailer. I figure that they will both be roughly 26”x75”, made out of 1.5” square aluminum tube, skinned on one side with the charcoal gray aluminum, and the other side will have some sort of solid surface (white lexan?) table top. What I am having a hard time with is how to robustly attach the doors/tables to the back of the trailer so that 1) I don't have to worry about them falling off, and 2) the table top doesn't have some large protrusion or sharp aluminum trim all the way around it. Sorry for the rudimentary cad, I haven't updated it lately and the software has some bugs that make it a bit hard to use.
In addition to suggestions on the rest of the design, I was hoping that someone might have some good suggestions on how to weatherproof and secure the back hatch. Construction begins when I finalize the plans and we get some warm weather so I can start the welding.
