We've always said that everything needed for a Basecamp should be stored and transported on the trailer. That's not always been the case. Our ever so lovely porta potti had always been relegated to the bed of the truck and getting stored in the garage when we were not camping. That had recently been amended.
We were originally just going to buy an angle tongue box. All the ones available were not the right dimensions. We even bought one we thought would work but it was wide enough the crank handles of the front Jacks hit the box.
We had a sheet of 4x8 aluminum diamond plate left over from the trailer build and a tig welder. What else is one to do? Learn to weld aluminum and build what you need!
Of course I couldn't just start out cutting and welding the metal. I had to do a trial with the old fashioned CAD program
Once I had the CAD box correct, I simply deconstructed it, laid it out on my aluminum and traced it around. You'll notice a big circle on the backside of the plate, that's a leftover "arena" from our daughters Governor's School project. It involved roughly 20 mice, testing their curiosity (or lack thereof) dependent on living conditions. It was interesting but I'm kind of glad the mice found new homes....
After the cutting all we had to do was bend the main body on the brake then weld the one seam, weld the bottom on and attach the lid to a hinge. Easy Peasy.
Here it is in all it's glory! My first aluminum welding project. It holds the porta potti, outhouse/showerhouse, and all the necessary accouterments for said potti.
We call it "the poop deck"
