when you say "stealth", I assume you mean parking on a city street or residential under a tree somewhere. Anything longer than a full size pickup or van is no longer stealth under that definition.
The best "stealth " camping is a full size pickup with lo-rise camper shell or a van made up to resemble a dog groomer.
The city of LA got wise to that and there are No Parking signs for anything over 6' (My pickups with shells have been just under. The dog grooming van... maybe?).
Otherwise you're just "blacktop boondocking" (Walmart, Cracker Barrel, etc, which I'm gonna assume most on this forum would consider).
So, what did you
mean by "stealth"?
