Interior Design

So i was thinking about what we could do with the inside/outside of BAMF. Im my camper there are about 5ish signs that my brother stole which my parents blamed me for stealing so i am claiming them as mine. i was also thinking that for like on the inside using chirstmas lights or maybe some of those crazy lights. Hobby Lobby is having a sale so i will have marsha pick us up some. Please let me know if we want to do anything else in BAMF. Also i know we need to either treate the wood, or paint the outside. please let me know what we want to do so i can pick it up and have it for when we want to finish BAMF.
