Newbie with a trailer.

I just bought a Carry on 5X8G utility trailer. I would like to build a teardrop that is removable from the trailer. I still need the use of a utility trailer. Any ideas.
I used to rebuild communications shelters for the army. They are tied down with cables on each upper corner. That's my idea anyway.

Consider foam construction. There is a whole section here on that. A foam cabin that size would be very light and easily removable. Several completed builds like this on the site.
