Del does not follow his own advice, AKA Cummins Whale

Made some minor headway today. Removed the fifth wheel brackets from the bed, which required removing the (very heavy) spare

AND I may have fixed the heater/ AC. Vacuum line dropped out of the vac pump connection!!! I havent driven it, but started it up, warmed it and moved it, and it seems to work "as expected." AC compressor cycles, so it's low on refrigerant, but not completely out

Still not sure on the oil leak. It does not seem to have blowby, but it has a phony plastic breather/ vapor separator catch can up front. It had maybe?? 2-3 tablespoons of oil in there, which I drained. You are supposed to drain it 'every so often' What a POS!!!! Chrysler Fiat/ Cummins? YOU COULD NOT AFFORD A REAL CAN WITH A DRAIN PETCOCK??
