First, welcome to the site. Lots of good folks and good information here
Our '14 is pretty dull except for the repainted front cap. For whatever reason it didn't get more then a passing swipe last year. This spring it will get a complete cut and buff to restore the nice look.
Most automotive detalers just don't know how to restore a good look to a very large RV. It takes significant time and effort, some heavy duty tools beyond a clay bar or DA buffer - polisher. It may require strong polishing compounds - and possibly a product like PolyGlow to bring back that color.
If you can't do it yourself, find an RV or marine repair shop that can do the job
