Nice job Stan. You have way more patience than I do. I have the same issues with the stripes on my 25' TT but figured when/if the time came I'd take it to a guy that does van graphics, I think they call them wraps? Either way it will be a few years yet. Your application looks great.
Wraps ain't cheap. If it's just stripes, no prob. Lay out the stripes with painter's tape, paint the stripes, pull off the tape. Cheap, easy, and as accurate as you are. For a decal, I'd just put the design on card stock, cut it out, put it in place, paint. Easy peasy. AND you can honestly say you did it yourself.

Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
