    Not sure what to look at first. Leveling valve?

    Just notice that the cab bags aren't airing up. Rest of the truck has air no problem

    There should be a pressure regulator between the air supply and the leveling valve. Often these get gunked up over the years and do not open to allow air to pass. Break the air line leaving the regulator to the leveling valve and see if you have flow there. If not, need to replace the regulator. If so, it must be in the leveling valve.

    Got it. Is that regulator in the same area as the leveling valve or in a different location

    I'm not sure on yours, but on ours they are mounted right off of one of the tanks. If you chase the supply line to the leveling valve back you should find it.
