I have a new Newmar Motor Home. Where is the best place to put the regulator? At the actual city faucet or where the hose connects to the motor home or does it matter? Also, how do I switch to city water once it is connected. I have the city water connected right now but the motor home continues to pull water from the water tank.

Thank you for your help.

I have a short hose (5'), first then the pressure regulator (one from HD or Lowe's not camping w) then my hose to the RV. Turn off you water pump when you're hooked up; then it can't draw from your tank.

If you put the regulator on the hydrant, you then have reduced pressure in the hose and the RV. If you put it at the RV, the vinyl hose is under full pressure and could burst.

^^ exactly!

I have a 60# max warning label above my fresh water connection. I also made a mechanical pressure gauge to check the incoming water system. 95% never hit 60#.

I check the pressure before I connect and yes, rarely have I seen more then the rated 60#.
Your water pump runs when it sees a decrease in pressure. So if it runs when you are hooked up, you have a valve open that is causing the pressure drop.
Check the fresh water fill, black water tank rinse, the winterizing valves (these are the ones in the water bay that are clear plastic lines)
When all valves are closed the pump will run until it reaches it's set pressure and shut off. If you open a faucet, the pressure drops and the pump starts.

Don't feel complacent with pressures under 60 #. A pressure regulator can also protect against surges, as when someone on the same line has water fast flowing then shuts it off. This creates a 'water hammer' or surge in pressure than can easily burst a vinyl hose, especially if it's been softened in the heat of the sun.
