That's an awesome lookin 3.4 Runner. Mine is still a stocker pretty much. How do I post pics on this site. Want to post something here.
Thanks for the input about the idle oscilation. Coolant is fine. Still looking for a vacuum leak. Checked TPS too and it seemed within tolerances.
As far as camping/sleeping in the back of a Cherokee, I would take out the rear "seat" and leave the "back". That would add some room. Then move seats all the way forward--place twin inflatable mattress and have a go. Trouble is that the armrest would get in the way which sucks.
