What did you do to your Class A MH today???

Received my Cummins Service Manuals and fuel filter today and started reading them. I still need to get the Oil Filter and change the oil. Last Lab Report recommended I change due to High Wear metals. Could be from the few hundred miles it was run with the air compressor suction hose off and sucking unfiltered air. Change this spring and re-sample in the fall. Reading the Manuals answered a lot of questions I had. I will take one to work tomorrow and read when I am on break and lunch. The Fumoto Valve came on Monday along with two new tire pressure gauges. One Cheap Mechanical and my third AcuTire Digital. If this one fails I do not know what I will be able to find that will be digital. I just seem to get them out of warranty and they fail. Last one was the display where some segments of the 10s digit would not work. Hard to tell if it was three or eight or 9 and this sucked. This is Acutire's last chance.
