Saw this on my local craigslist - Never saw this done before

When I was much younger, my parents neighbor took a pup and converted it into a vendor trailer where they sold photos. They were the "official" track photographers at several of the late-model and hobby stock race tracks around central Indiana. The hard board sides folded down and the lifting mechanism still raised and lower the roof. On the inside of the 3 walls, they made slots (like sliding picture frames) for different sizes of photos (of the race cars) and winners of each heat from the week before. The front side (where the door is), they made a flip top counter, a comfortable height for anyone standing on the ground. Pretty creative to say the least.

I love it when people use their creativity and find ways to "recycle" or "re-purpose" older or unwanted RV's of any kind!
