I recently purchased a Dutchman Infinity 5th Wheel with a Fifth Airborne Pin Box and am not sure how to adjust it. Do I adjust the air until it lines up with the line or do I need to measure the air pressure? Any advice will be greatly appreciated.

I have one of these pin boxes and I have always just put in air until it lines up with the line. That is what the instructions said when I got it. It has always worked well for me.
Yep. That's all I do. Load the trailer the way you would to travel and get the full weight on the truck then line up the lines by adding or subtracting air. Then hit the road.
