RE: Stealth Camper
A friend of mine, a guy I worked for many years ago, has done something
similar. His is on a box truck, looks just like any service truck when
parked.  But on a 4 wd chassis. And the usual box on top, forward at the
cab, that usually holds an AC setup, has a generator in it.   I'll try to
remember to take a camera next time we get together.
