Faulty pressure switch on pump.
When you open a faucet the ON-Demand pump should start almost immediately due to the instant drop in pressure, same if leak occurred and no pressure in line.....pump would start build pressure.stop repeat when/if pressure dropped
Pump would cycle repeatedly within short amount of time if pressure dropped provided the pump PRESSURE SWITCH was working.
When pump does run how is flow/pressure?
2011 camper probably has a Shurflo Classic 2008 pump.
That has been discontinued so any parts would be Old Stock
Pressure switch can be changed but easier and not much more in cost to replace with a Shurflo Revolution 4008 (little higher flow and bit higher pressure 3 gpm/55#)
The OP's pump is running just fine. The complaint is that there is no residual pressure with the pump OFF. This is a leak on the pressure side, either something is losing water into or outside the camper or (more likely) just leaking back through the pump.
Granted could be pump internal check valve leaking but if pump is turned on the it should cycle on/off on/off. If it doesn't then pump pressure switch is also issue.
If OP is tuning pump OFF then .....leak and that could be check valve
I rarely turn an ON-Demand pump off unless I leave.
Pump cycling with no demand alerts one to a leak.
