Yep, Mel is right. Paint it the way you want it to look.
HOWEVER (and this of course my own personal opinion and others will undoubtedly differ even if they are
completely wrong 
), curvy lines running down the sides of RVs...well....they look pretty bad. RVs are short from spinner to rudder and adding a bunch of curves just makes them look shorter. These are little hotrods and they should look like it.
Every RV has fantastic "lines" in the profile of the design. You don't need to spruce it up with fancy paint and lines running everywhere in every direction. Keep the paint scheme simple. I believe the simple ones are the most timeless, and that is exactly what I was aiming for.
Of course I am *completely* biased.
