Okay, so I really dig the Winter Warriors, but need a design that's small and light enough to be removable. At other times during the year the bare trailer will house our Yakima racks and be used to haul our kayaks, bikes, etc. Still working on the most efficient way to affix/remove the cabin since it will still be a few hundred pounds, but first I wanted to at least get an idea of what the design would be like so I had somewhere to start. The attached plan is the beginnings of my vision for my modified WW Jr.
The cabin interior is JUST large enough for a queen mattress and that's about it. The floor, walls, and ceiling will be 2" Foamular 600 sandwiched between 1/8" ply. I toyed with the idea of a foam/canvas TD, but will have to see one in person before I decide to go that route or not. Ply blocks will be positioned within the panels to act as mounting points. There will be a vertical and horizontal "shelf" to help act as a cross-brace. I'm going to try 1/8" ply for the side skirts adjoined to the hatch, but might need to go with something more substantial (hopefully no more than 1/4). When in transport, the hatch will be all the way down, latched, and pegs of some sort will help stabilize the side skirts. For three seasons, we'll raise the hatch up 30 degrees and peg it in place. To save a bit of weight, the opening will have tent screen and zippered tent fabric that will be rolled up during transit, but then unrolled and affixed to the walls. We'll also have rolled up Enerflex radiant barrier that can be lowered for times when the weather becomes a bit more extreme. A tent door (tent pole framed) will be able to attach to the top of the solid door to allow for easier egress. During colder weather, we'll probably bump the hatch up only 3 degrees so the solid door can opened, peg it in place, and use the tent mesh and radiant barrier to keep temperature exchange to a minimum. One thing to note, in the final plans the solid rear door and wall will be taller. Not sure how I messed up the calculations on this one, but it was intended to be about 3 or 4 inches taller. I didn't notice until I was too far into the design to bother with it, since this is just a mock-up.
Would love any feedback from those who have traveled this path before. Any glaring faults in my design (other than the obvious lack of trailer and missing one side of the hatch) ?
