I know I have seen them, twice, on two different rigs, one in No. Cal and one here in Seattle. I did not get close enough to examine them, looked like a really cool idea. Maybe tha folks that make mini truck campers would know. Seems to me I saw an article in FW &OFFROAD several years ago about a camper specifically for 4wheeling, or adventuring, or something like that. Get back to us with links or pics or whatever.<br><br>Dan
