Update. It's been a while but I'm finally starting to build. I used my trailer as is last fall for a quick trip, just used cots, it was nice to stay dry. Parked it in the yard for the winter. A couple months ago I decided to have a peek inside and to my horror, the plywood on rear portion of the walls on both sides was saturated with water and mold was starting to grow!

Called the sales place and they told me to bring it in right away. After a week, they called me back, they had fixed the problem and it was ready to pick up. A few weeks later, I had another peek, the plywood still looked wet on one side. I decided to investigate myself this time. Pulled the plywood off and sure enough, still leaking under the window. Brought it back a second time. Lots of apologies and ready the next day. Bring it home and since the plywood was still off I figured I would test it again, just to be sure before re-installing the plywood. Get the garden hose on the roof and window, within 30 seconds, its dripping under the window!

Brought it back again. This time the owner is pissed and calls the repair shop at the back. By the time I drive the trailer to the back, I have the shop manager and two guys waiting for me. They're going to take the window out, re-tape, re-caulk, etc... Finally, it's fixed. Turns out it was actually coming from the roof and running along the window. So every time they were messing around with the window, they were missing the actual leak. The shop has been good with me, they gave me a jack extension, a wheel lock, a bunch of extra trims to fix everything.
Ready to build now. One thing I noticed when I pulled out the plywood looking for the leak is that the builders were very sloppy with the insulation. Missing complete sections and just putting in random pieces of foam that kind of fit but not really.



First thing I did was take down all the trims and plywood. Kind of frustrating when I paid extra to have in insulated and trimmed to avoid having to do this. I kept the original Styrofoam and supplemented with some new one. I don't think the foil and green plastic cover makes much of a difference insulation wise so I just filled in the gaps and replaced the damaged or missing sections.


I'll fill in the smaller cracks with spray foam when its time seal her up again.
Installed two LED porch lights, one on each side.


I have other goodies in the shop waiting to be installed once I'm done with the insulation. I build a sofa/extending slate bed that will take a queen size mattress. I have a roll of vinyl HDX flooring from Home Depot for the floor. A Vortex vent fan and a Dickinson P9000 gas fireplace that I'll need to wire before re-installing the plywood.
I was a rough and frustrating start but I'm starting to make some progress. I'll post more often now that I'm making progress. Thank you guys for the ideas and inspiration!
