An air compressor, I drove from the Keys to W.V. last month to hunt and fish on the New river. The tire pressure sensor light came on the first morning with the cooler temps, all tires needed air.
I slept for an entire week in the back of the T4R. I'm 5'10" and fit pretty good corner to corner with the seats folded, though I wouldn't recommend it for anyone over 6'. Which reminds me of a major annoyance, if the keys are not in the ignition you can't use any of the interior lights after they have timed out.
Now where did I lay that flashlight :bash:
Also, since the door openings face down I was amazed at how much mud gets up in there.
Othewise the T4R did great pulling a loaded 17ft boat up and down some pretty nasty dirt roads.
Good luck on your trip
