There was a guy down the street that had his Jeep CJ8 done in the camo wrap. It was really expensive.. something like $3,000 to $4,000 dollars. It started to get knicks in it and began to peel so he ended up taking it off after a few years. It looked good on a Jeep, but I'm not sure how it would look on a trailer. Make sure to put deer hunter orange somewhere on it so people don't shoot at it or bears don't run into it. Also, I can hear it now. "Mr. Park Ranger... I know my trailer was parked here somewhere but now I can't seem to find it."
I live in texas and I promise you I'm not making this up but they actually sell camo'd house furnuture here.
