Air Ride Pin Box
Bought a use "Trailair" pin box. There is no paperwork and I can't find a chart at manufacturer website. I am trying to find out the proper amount of air pressure. My hitch weight is about 2000 lb...

If there is a yellow arrow saying "inflate to this point" you should use that. I have never found air pressure (when the trailer is unattached)to be reliable .
If you do not have such an arrow, I would inflate with the trailer attached (weight on tow vehicle) -- inflate an inch or so from the top of the shock absorber and make a clearly visible paint mark there, then use that mark as your inflation guide.
^^^ That would be real close to where my factory mark is. 70-75 PSI hitched is what I run.
