Now that I have managed to get the floor down and the trailer fixed, I could actually start framing. Which is something that I know I can do. I still need to get some epoxy to fiberglass the inside of my new wheel wells before I secure them down so I could not work on that portion of the wall framing, but the rear of the trailer is up at least.
I also have built two of the other wall sections not to mention cutting the wood gor another two aread. I can erect them once I have that fiberglassing done. (The benefit of doing the wells this way is that I get lots of practice for my ofuro making later.)
Time to decide if i want a sliding glass door on the front or french doors. (Space vs looks, really).
