Just to be a contrarian... :B
Probably 75% of our camping is boondocking and we use the heck out of our pump. I think I've only replaced the pump once on any of our rigs when it developed a leak on one of the connections. (It made sense to replace it when I tore into it.)
But we never use the pump when we have full hookups. I'd much rather use the silent water service from the camp. We've probably logged a few hundred nights with FHU and I've gone through a bunch of cheap pressure regulators, but we've never had a pressure related failure. I wouldn't hesitate to keep using a regulator and take advantage of the silent water hookup and give the pump a vacation of its own. Yes, I'll switch over to our fresh tank if it's too cold for the hookup, but that's an exception and not a habit.
