RJ.....Just like my coach, yours was painted with lacquer back in 2005. Most states only allow water base paint now. Mine was painted with Sherwin Williams paint and they couldn't even cross reference the paint codes anymore.
Your best bet is to find a removeable part like the refer or heater door that has all of your colors in it. Take the part(s) to an automotive paint supply store. They'll scan the color, just like Home Depot, and you can have some small cans of touch-up paint made.
