I recently replaced some of the decals on my travel trailer. After looking high and low for an expert on the subject I found a local shop that does decals on cars and trucks for advertising purposes - the kind that sometimes cover the entire side of a panel truck. He asked me to bring the trailer by for a look. He took measurements, worked up a cost estimate, which I thought was reasonable, and spent a week or so preparing the decals from scratch using his computer. I brought the rig back a couple of weeks later and he installed them. Keep in mind he was matching some of the decals left on the rig. The colors were perfect and you could not tell his work from the factory work.
