22' cargo trailer conversion

Hey guys im new here. I found this site while googling trying to find ideas for my trailer. I have a 8x22 that im wanting to convert into a camper/toyhauler. I race 300' ATV sand drags, so im looking for a home away from home when im out at the races. I bought this trailer last september and i threw something together to make it to a race in NC. I stayed in the trailer for 4 nights and it was nice, but i would like to make it better. The trailer is already wired with a 30 plug on the outside and a small breaker box on the inside. It has 2 8ft light fixtures in the ceiling, and the wires are already ran up to the roof vent to hook up a rooftop a/c. It also has a few receptacles. Heres some pictures of how it looked when i bought it.
