Question:

Whar is the initial air pressure for the donut on the 5th wheel hitch pin box LC328492? When we bought the trailer the yellow sticker was painted over so we cant see what it is.

Step 11 of the installation details (which are linked) for the Trailair Flex Air 5th Wheel Pin Box # LC328492 state to:

Inflate the air bag with only enough air to raise the pin box to the ride height mark on the front of the shock absorber with the truck and trailer at rest.

Overinflating the air bag could cause it to burst and cause some serious injury to you or those around you.
