We purchased the trailer to store and haul our two quads, and will be working on converting it into a very basic toy hauler / camper this weekend. My current plans are to add a roof vent, RV door latch, recessed floor d-rings, vinyl floor, interior lighting, fuse block, convert to 7-wire, build a moving bed platform that can double as a long couch, figure out under trailer ramp storage, and add three windows (one in side door, one one each side of the trailer).
Sounds like a lot for a basic conversion, right?

I got the roof vent and RC latch installed a few weeks ago, and we tried sleeping in it on the floor on air beds to see if we'd like it vs. a tent. Well, we're hooked!
Ordered foam for the mattress yesterday - so that will be the "big" effort during the next few weeks to make a cover and a bed platform.
I'll attempt to keep this thread updated as I go - but fair warning, it will be a slow process.
Here's a pic of the trailer behind our truck:
