That's awesome! A few common issues I've seen so far with the trucks coming out of Barstow are:
1. The front hubs have water in them. See the videos I have posted.
2. The air dryer purge valve seems to stick open and drain air. This can be temporarily fixed with adding a small rubber washer stacked in top of the existing
3. They are almost all out of fuel. Plan on hitting the truck stop fuel station about 1/2 a mile East on Outer Highway Rd
4. Heater switch. The local O'reilys should have one. You'll need a small flat head screw driver to remove the push pin clips, then a 14mm socket to remove the nut on the switch.
The guys at the yard can be cool. If you go at noon they'll all be gone at lunch. Take your paperwork to the metal building and ring the bell. Do not go into the yard past the barbed wire fence. They get all pissy if you walk in.
This was AFTER my 1st drain/refill. The 1st time I drained it, pure water came out
