Picking up my bus tomorrow

[BusT]

So I’ve been posting on here awhile and lurking . Under different accounts . Also bangbus... I know.
I’m from Houston heading to Orange County California .
Picking up a dt466e
2003 Thomas flatnose
Allison 2000
Airbag suspension in rear.
28ft
183,000
Before tony from the aaa buses got it it was supposedly from Vegas.
Previously from aaa buses in phoneix , the owner as of January decided to sell it. So here I come.
Any suggestions before I take off back to Houston 1500 miles with this new bus.
I plan on checking coolant and keeping eye on temps.
I plan on checking for milky looking oil.
Tires . Air pressure in tires.
Whats the right psi I’m looking for 120 in air break system ?
Also why are the tires looking shorter in the back then the front? I’ll add pics once it’s mine.

Air pressure should be around 120. You will (should) hear a beeping if the pressure drops below 60; you'll also see a swinging red warning arm come out top middle of the windshield. If this happens while driving, get off to the side ASAP because your brakes are about to lock up. If you hear this beeping on startup (and assuming the pressure comes up to 120 in a few minutes) it means the bus hasn't been run in awhile and all the residual pressure has leaked out.

So what if the pressure did leak out... will it build up again and be good to go?

In the has t been started in awhile scenario...
Got it if my air breaks lock up. Pull over.

If your air system is OK, it will build pressure back up and keep it there when the engine is running. Nothing to worry about as long as it doesn't l pi ar 0ressure immediately...
