I own a 2025 4120 GK Redwood. I don't know where the overflow tube is for my fresh water tank. There is a hose towards the rear of the rv but it has a shutoff valve on it. My 2016 Redwood had one closer to the front no shutoff on it.
It’s been standard now for a number of years located in the docking station. It’s plumbed to the upside down “U” shaped cover that deflects overflow down in the docking station. You can pull the cover off and you’ll see the end of the FW vent hose. Overflow will collect in the floor area but will drain out from the floor cover if it is open (which it will be for the fill hose entering from the bottom).
Thanks for the information, found it. Do you know that the hose hanging down in the rear of the unit is for? It has a shut off valve on it. When I opened it a drop of antifreeze came out but nothing else.
I have a different unit (2020 3401), but one drain is from the FW tank, and one drain is from the water line to the fridge for the icemaker. On my unit the water line source and valve is from under the kitchen sink. There are numerous stories of owners freezing these lines and so ive left mine isolated and drained and never used it.
i also have a hot and cold water line drains hidden up behind the bottom side skin by the docking station.
