Finally I believe the leak is resolved
Ordered, received, and installed a SUREflo 182-200 Pre-Pressurized Accumulator Tank under the roadside hanging closet near the pump with a 1/2" x 1/2" x 36" FIP reinforced PVC Faucet Connector from ACE Hardware. The city water port-pressure reducer assembly arrived from Airstream under warranty which I installed with a 1/2" x 1/2" x 30" FIP reinforced PVC Faucet Connector with a gender changer on the interior side connection of the port to reduce stress. For about $60 I believe the leak is behind us........for now or until encountering the next pot hole. Thanks to everyone for your expert advice.
