Alright you guys, lots of folks are viewing this topic, but no one is answering up
This is MY opinion or 2 1/2 cents as you prefer.
If I was going to paint two-tone, I'd carry the color at the same height all the way around...if the trailer has a natural break or belly band.
I'm going to paint my Scamp in the fall. My pickup is painted Silver Frost, but the new-old tug I'm building will be painted a soft yellow. My painter is refusing to paint the trailer yellow. (actually he will, but really doesn't want to). His thought is when I tow the trailer with the pickup it will look

And secondly, if I sell the yellow vehicle, I'll end up with a yellow trailer..what's the point if it doesn't match anything.
Paint, while not a bank breaker, is not cheap and I only want to do this once. My painter's suggestion is to paint the trailer white and use an accent color (YELLOW) as a wide stripe. If and when I replace the yellow vehicle, all I'll need to do is change the stripe color, not repaint the entire trailer. Besides, if I ever decide to sell the trailer (

), white trailers seem to be preferred by more buyers.
Okay, so that's three cents worth of information.
I want something similar to the attached pic...with matching wheels too!!
