I am in the middle of a renovation of a conversion I have been working on for about eight years. I purchased a Haulmark in 2002 to transport an ATV for Search & Rescue missions....we average about 60 or so a year that involve ATV's, so it is nice to have everything in one place. Over the years, I had added insulation, a front cabinet, dedicated battery, and painted the walls and floor. This past October, I decided to re-do everything, and construct something that better suited my needs for over-night SAR missions (along with camping) by adding more storage, upgrade the lighting, add a stereo system, and give everything inside a "cleaner" look. The first pictures show what the trailer looked like last summer after I painted the floor.
As you can see, it works, but I felt it could be more functional. Add a large ATV into the trailer, and you really cut down on space.
When I started to tear things apart this last October, my first concern to address was the problem of dirt-road dust entering the trailer. I had heard from friends that the area in the front of their trailers (all Haulmarks) were very poorly sealed - with large gaps for dust to enter. Seems mine had the same problem, as you can see by the poor picture - the white streak is an air gap about 1/2" wide. I sealed the whole front area by the floor with foam, and also along the entire length of the side walls. I have read on this forum about the problems with using rolled insulation, but the area in the front of the trailer uses both rolled and 1" foam board, since there was a large area to fill. If I were to do it over again, I'd probaly just double up the foam board.
I'll post further details as soon as I upload more pictures to my album.
