Although this is an old thread, I thought I would toss my two cents in. I have a Palomino Bronco on a long bed king cab F250. I have it because the person who sold me the truck told me she wasn't going to take it off. So from a spartan camper on my old truck 2004 Ford F350 Diesel, I now have hot and cold running water, a commode, a shower inside and a shower outside, furnace, threeway fridge and AC. Pretty plush for me, a long way from the granite mountain ledges and small tent out in the Sierra with Doug Stewart and other wanderers.
My All Terrain Camper shell is way plusher than that mountain ledge but only slightly fancier than that small tent. The nicest thing is getting out of bed by standing up!
