Valterra A01-1114VP Hi Flow regulator
Picked one up, stainless steel, pricy for a water pressure regulator, but WOW, worth the $19 I paid. Pressure inside the last two campgrounds, traditionally low was significantly higher, but rig still protected. Wish I had gotten one years ago. Next time you need a regulator, check this product out. Wife no longer complains about low pressure in the shower and kitchen sink.
