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.
