[2017-303RLS]

I just bought a new to me 2017 Grand design Reflection fifth wheel 303RLS. When filling the fresh water tank to go to a park without water hook ups, how can you tell when the tank is full. There has got to be a better way than to keep running from side to side looking at the red dot water level gauge in the camper. It has the nautilus water management system. Thanks in advance.

My 2019 Momentum has overflow hoses, that do exactly that: overflow when the tank is full. Yours is older but seems like it should work similarly.

I usually take a beer with me, and betweens sips of the beer I push the button to check the level. Works everytime

Listen for the splashing on the ground

My overflow hose is close to the door for the nautilus, easy to hear when it was full.
