Do you know what the water pressure is at your house?
I think I'd get the pressure regulator. They aren't all that expensive, and as mentioned, "cheap insurance"....and while you plan to keep the RV at a single campground, at some point, you may want to travel with it.
Same goes with the surge protector. They are more expensive, but if you happen to get a voltage spike or low voltage that could damage your electronics, it will more than pay for itself.
If you feel that the CG you are staying at will have a well maintained power system (most don't:() you could save your money.
I don't understand why RV mfgrs don't install them as part of the OEM. They could pass it along, but at some point, if they all do it, we're gonna buy them, and possibly be safer for it.
