Black vs White paint

I've toured a couple of RV manufacturing facilities. Many builders buy the exterior fiberglass large sheets (gel coat, color coat, fiber glass, plywood backing and maybe foam insulation) and trim them down for what ever the current production run might be. Sheets are prefinished in what ever color the builder ordered, usually white but more rigs are coming off production in grays or browns. As such other than decals or other such embellishments no further work is needed and the coach is headed to the dealer after about 5 days of production build out. Fully painted rigs, add an additional three weeks to the process and a many, many hours of labor rolled into the cost to the next and future owners.

Black and darker colors are hotter in the summer, while white ones are cooler.

Living in the desert, I'll be content with the alleged cheaper white paint or white gelcoat body.:B

As for White being cheap....this isn't MY idea of cheap.... Hallmark 4501 - $ 527,771.00

our coach doesnt show the dirt. everyone knows a darker colored vehicle will show the dirt a LOT faster than a light/white colored one.

My wife's black miata shows ever bit of dust, where the white jeep looks clean (even after towing it 1500 miles). Im always amazed at the amount of dirt on the jeep (after a 1300 mile run to virginia)...never realize how dirty it is til i wash it.

The problem with a white motorhome is dirt. Our brown, beige, and black swirls hide road dust, dirt, and rain spots better which means we don't feel compelled to wash it as often. Do I like all the swirls? Not really, but I wouldn't prefer an all white generic looking coach either.

More and/or bigger air conditioners.

I think what you are seeing is full body paint VS white gel coat and decals which is much cheaper. Automotive paint is very expensive as well as the process to apply the paint. Most of the painting process is in surface prep and masking to spray. White gel coat requires none of this. Also on new model MH's full body paint usually is on the higher end models. Paint does protect the gel coat underneath from sun damage but darker colors absorb the suns rays and create other problems. Personally I would rather have a white MH with a white roof and earth tone door areas below for cooler summer travel.
