Like Buzzcut1 shared, I too have my (L & R) Shrader Valves on the passenger side of my truck. They are plumbed seperate.
In addition, I have $1 bubble Levels at the same location, both for front to back and left to right, so I am able to stand in one place, to level my truck. I also have another Bubble level on the inside passenger door of my truck. It is situated in the passenger door map pocket so it can be seen from the driver's seat and not from anywhere else. This allows me to get into a location, pull in and get my truck pretty good (front to back) before even stepping out from behind the wheel. It makes it a lot easier to have this before I get any ramps out, if even needed.
