I use two SHURflo 2088 pumps, the old-fashioned simple pumps that a SHURflo/Pentair salesman said are still the most reliable ones they make. They're rebuildable if the pressure switch karks or the diaphragm leaks, but normally they'll last many years without a hickup. I have a Watts DET-5 expansion tank to reduce hunting, and each pump has a SHURflo 255 strainer to keep solids out of the diaphragm and pressure switch (a common cause of pump failure).
I use a Watts 263A pressure regulator to ensure the incoming city/campground water pressure won't ever exceed the bus's PEX lines' SWP, and with this and a pair of pressure gauges for the city water and onboard water I can easily set the pumps to the same 45 PSI as my city water. This way the shower/sink/hand basin water is the same flow and pressure whether it's from the tank or from outside.
