Hi TNcanuck,
I am glad to read that someone has utilized my LED conversion idea. Thank you for sharing that.
As far as the graphics are concerned, the only thing I could think of is to call the factory and see if they have some suggestions. Who knows, they might have replacement graphics on-hand. Removing the graphics and paint your entire PC might be another option, worth asking the factory about. Get the phone number of the paint company they use. You might get better advise and price working with them directly to get a 2018 paint job. Another consideration is to work with a local RV paint shop in your area who would be logistically easier to work with.
The only issue with any paint work would be the matter with the old caulk. That would be my biggest question to ask about for repainting. With our full body paint PC, our paint work is over structural caulk, but might be under other caulk like surface-mounted items like lights and such. If cleaning off old caulk, I wonder if paint will stick to a surface that was previously caulked...pending the type of caulk.
The same may apply with your graphics. Some of your graphics might be behind caulk at corners and such. In the end, you might conclude to leave well enough alone as not to disturb critical caulk work.
