Just bought a 2014 3850FL and it is great. One issue though is the on demand hot water system. It is a Precision Temp Model RV-550.
It heats up the water just fine to start a shower - maybe too hot! But after a few minutes it turns cold. Then back to warm then back to cold. If I leave the flow of water restricted it will stay warm enough to finish the shower but that is about it.
Propane tanks are full. Water pressure at the trailer is about 42 pounds. Any thoughts?
