Well, I made a lot of progress but haven't kept up with this site! Here is a bit of pictures of my "finished" trailer (When are they ever REALLY finished though?)
Unfinished hatch and interior shot:
Painted side shot:
Hastily finished back area:
I like this least of all the trailer and it may be redone before next summer...
Skylight and the two solar panels, these are the only source of power for the entire cabin:
Straight shot from the door to the other window:
I may also just make square windows. I feel they would work better in the long run, though these work perfectly fine. You can also see the two LED spotlights which also hold the large rechargeable batteries. These suckers light up wherever you point them. Very easy to read by.
Shot towards the foot of the bed:
The bed ended up being two 2' wide pieces of 3" foam, 6 feet long and a 2.5" memory foam topper, full size, all trimmed to fit. If you shop for the sale at Joanns and look at Walmart/Ross for the cheaper toppers you can get it set up for $160, which was about the prices of inflatable mattresses for this size. After two nights on it, it was pretty comfortable. Don't confuse this with my mattress at home but for camping, much better than anything I've had before. And I didn't cause the fiance' to roll into me like on an air mattress.
Again, the lights worked wonders! I couldn't be happier with them. And I think they look pretty tidy.
The sealant on the outside is Koolseal, an elastomeric paint meant for RVs that I rolled on the sides. I used two gallons to get good coverage and so far no leaks, but also no real storms. It will be outside without a garage all year long so I'll through a tarp over it most the time.
I finished the floor by just dumping fiberglass epoxy on it (after mixed). It made a fairly thick covering that is very easy to keep maintained.
Let me know if you have anymore questions but after a weekend in Yellowstone with GORGEOUS views of stars one night and a storm another, I'm pretty happy with it!
Thanks!
