Love what the OP has done here....I have something similar, and I too was at one time dreaming in the world of "stealth". Having a white "commercial vehicle" standing just about anywhere can go quite un-noticed, but there are plenty of challenges in this post DHS world and everyone on edge. First, you would have to keep it registered as a commercial vehicle and carry commercial insurance. Usually this means as much as 4 or 5 times the cost of a traditional camper or motor homes yearly costs. In may states, it also means DOT registration and inspections, all for a personal vehicle that has no commercial ties. And as I can attest, when you have an insurance issue with your personal use/commercially insured vehicle, there comes all sorts of questions as to what business the vehicle is used for, which is none ! Really gets the agents confused !
On the other side, if you have a personal vehicle engaged in what appears to be a commercial venture, then the DOT is bound to pull you over (like if you put a business name on a personal registered vehicle to help disguise as a work truck). You just can not win anymore !
Again, I too started thinking stealth and that went south when I knew I would have to license as motor home in order to afford to have my rig in the first place. "Stealth" took the biggest hit the minute I mounted aluminum wheels. After that, the solar panels on the roof and a TV antenna (even though I did all I could to make it low profile) took away from that "commercial stealth" look as well. Oh well !
I'm a huge fan of retrofitting "square boxes".... lots easier than the other options like busses..... True "Stealth" is likely only achieved by using nothing larger than a very plain conventional cargo van with literally nothing screwed onto it. I tend to like a few more options than that.
