Water Leak
Titus is sitting in the driveway with a slight nose-up orientation. Turned on the water pump and checked things out in preparation of upcoming usage. Hours later I saw some dripping from immediately in front of the road-side rear wheels. Water was dripping from the Sprinter body about a foot uphill of the wheels, and running down the channel at the bottom of the Airstream-added bottom panels. Pulled out the bottom drawer, removed the microwave, and removed the panel behind the tall skinny cabinet to gain access to (or at least visibility of) all the plumbing that was up-hill of the drip. Eventually found the leak at the back-side of the shore water hose fitting. The threaded connection on the back-side of the fitting/check valve was loose. Male 1/2" NPT on back of fitting/check valve. It is located behind the refrigerator but I could reach it without removing the refrigerator. Tightened it by hand (1/2 turn at most) and the leak stopped. Not sure what caused the loosening and leak after 5 years and 63,000 miles, but apparently it is something that should be checked occasionally. While in there I also checked all other threaded connections (back of outside shower valves, water pump connections). They were all tight.
