In a new unit, used only six times, there has to be a source of moisture/water. The water heater is a sealed unit. There should be zero moisture being introduced to that are to cause the need for ventilation. If there is moisture in there it is better to eliminate the cause then to vent.
In an RV in the PNW used only 6 times in 3 years the source of the moisture is the high humidity typical of the PNW. The unit likely suffers from the lack of being opened up regularly to dry out - hence, it molds.

I’d say this is 99% likely the case.
Ifnit sat outside uncovered for even 1 winter on the wet side of the mtns I could easily see this happening.
I have an enclosed trailer that sits outdoors 24/7/365 uncovered and from about Oct to April I keep a box fan running in it continuously at a minimum as well as a milk house heater for a few days after we go snowmobiling until the sleds and floor all dry out 100%.
If I don’t, the condensation is immediate and mold like this begins popping up quickly.
Just bleach wipe everything down that’s moldy, and keep ventilation in it during the wet season.
