Here is mine, a 2001 Dodge Ram 2500 quad cab longbed, Cummins 5.9 HO, 6 speed manual, 4.10 posi rear end. We bought it from the original owner just over a year ago with only 101k miles. Mine is 2wd so I can't go a lot of the places you guys go. But with a posi rear end, it will get me most of the places I want to go. It came with a 5th wheel hitch, so we are debating whether to go that route or get a camper.
The photo shows a trip last year in the forests of Humboldt County, CA. We camped in the bed with an improvised bedroll and some bug netting stretched over a PVC pipe stabbed into the stake pockets in the truck bed rails. It works great and we've been very comfortable with this setup so far! :smiley_drive:
