After connecting the water and turning on the water heater the pressure might rise in the RV if you use no water. It is possible that the regulator didn't fail. The regulator has no way of bleeding off excess pressure downstream.
Shouldn't the pop off valve on the water heater relieve excess pressure?

Sure, that'll work. The T&P valve will relieve at 150 PSI.
Excuse me, I didn't know the pressure had to be that high.
T&P Relief Valve will also open at 210*F
And will 'weep' when the air gap at top of water heater is lost.
Air gap is there by design to absorb pressure increases due to heating water (air can be compressed/water can't...water swells when heated)
