I like that color man!
If you want an simple alternative to adding stripes, mask the truck at the seam line above the door and paint the roof black. Go a bit further and mask the bottom at the seam line below the door, wrap the front and paint that black too. Will be just enough to set it off for a custom look without complicated striping. (Just a suggestion)
Don't forget to gloss coat the whole thing before you assemble the body.
Do you plan on putting a future stretch in it?
