^Thats sweet!
All this issue with dressing up a big white box with stickers could be put to rest and actually a big successful marketing tool for the first couple TC mfgs to catch on.
Colored gel coat doesn't cost no more than white!
Offer some classy muted neutral tones, even a few Monster green ones for the Glamis crowd.
Heck if you "order now" you can get any color you want! Color match it to your red, blue, purple haze colored truck for a slight up charge!
Doing 2 tone or sprayed in color graphics would not be cost effective since camper siding isn't sprayed like say a Fiberglas boat, but beige, gray, etc, colors that compliment vehicle colors, and colors that blend in, in a wilderness environment like where TCs are meant to be used would be huge.
Heck, still put your big logo and some grafix on the side. At least it won't look like a Ryder rental box truck when you take the stickers off!
