Bryan, On your air dryer, did you find the air leaks or did Cummins? Did you have any indication something was amiss with your air dryer (symptoms) or did Cummins pick it up during their inspection? The reason I ask is that our 2005 Patriot air dryer seems to work fine, blows off at 120# like it should, so I just am wondering if there are any warning signs for a bad/leaky air dryer?
BTW, we had our coach 4 corner weighed after we bought it and we adjusted the tag axle air pressure up a bit to put a little more weight on it; also put more weight on the front axle, expected, if you think about it. Anyway, that tag axle pressure has a great deal to do with your front axle weight, just a heads up.
