Should the Air Bag on a Trailair Air Ride Pin Box Be Filled Before or After Coupling to Tow vehicle

Question:
Should I inflate the hitch to the line on the shock while the camper is connected to my truck or while it is standing on its own?

When using a Trailair Air Ride Pin Box, like part # LC158778 that you referenced, you should inflate the air bag to the line on the shock once it has been connected to your 5th wheel hitch.
I have attached a review video where you can see this process being done at the 3:47 mark.
