I came across a problem last week. I seldom use my fresh water tank on my 2013 LS36FW because city water is available . The FW pump started to hammer when I run the water , the bathroom sink is the most noticeable. Everything seems to be in order….filter is clean, no leaks etc. Is the pump on it’s way out or is there something else going on?……Rich

My truck camper did that when I first used it after storage. I believe that it is air in the system. The truck camper had a convenient re-circulation loop that I could let it run for a few minutes, then run the water in the sink. In fact do both at the same time. Run the water slow into the sink for however long it takes to quite down. In my case the hot water was quite. I believe the hot water tank acted like a buffer. I believe that your pump is OK.
