Hey Jeff! For a quiet fresh water pump I recommend the Seaflo Diaphragm Pump # SE57FR. The Seaflo uses variable-flow operation, so it does not hard cycle on and off like a standard demand pump. That gives you smoother water flow with less vibration and pump noise. It is comparable to an indoor electric fan and uses a semi-rigid rubber base to help minimize vibration transfer.
What kind of trailer are you working on?

The old pump in my truckcamper cycled for a second or two every now and then from when it was brand new. This was a nuisance if we forgot to turn it off before going to bed. It almost seemed that it knew the right moment to pulse on to prevent getting to sleep. We replaced it with this pump. Spec's for pressure and flow matched with the original. Fit up was exactly the same as original, except that it had to be installed behind the sink and power panels while standing on one's head it was a breeze. (Fault of the camper layout, not the pump). This pump has performed as expected and we are no longer bothered by the cycling pump.
