I am building an Adventrure Trailer to put my Camping Lab roof top tent on.
It will have an on-board deep cycle battery, and lots of dry storage.
Started out with a stock, slightly used, Coleman VersaTrailer. I purchased it from a friend of mine for $200.
Building a Box
I built a 16 inch tall box on top of the trailer to create an enclosure for dry storage inside the trailer. This will also allow me to put my Camping Lab roof top tent on top.
The tubing is 1 inch square .120 wall.
