They also make a screen room for the rear of these trailers. I have learned after owning 4 of these that it is very important to stuff some fiberglass in the ceiling and cover it with paneling. If not you will get to much heat from the sun and on chilly mornings it will rain inside!
And if you need any E-track or floor mount D-rings or other trailer parts dont forget to call me. The E-track is great for attaching shit to the walls! I have one the fold up Lifetime 8' picnic table on the wall inside mine, it's nice to have when you dont have a place to sit and scarf down some camp chow.
