Crawl under the camper. Fresh water tank is usually white. Black and gray tanks are black.

Do you have a winter/thermal package which includes an enclosed underbelly? Maybe that's why you can't see the fresh water tank.

On your 5ver, it will be tucked up between the frame rails. Your underbelly sheathing is hiding it. Look for your overflow/vent pipes. The tank(s) will be close to them.

Agree with above, should be just behind the axels. Fresh water tank drain (not the 2 low point drains) and overflow tube will be next to it.

You can email Jayco support. Supply your vin number and they can provide blueprints showing the locations of your tanks. Attached is the info I received when contacting them on my 357MDOK. The dotted line boxes represent the holding tanks.

Thanks much for this helpful post. I've been looking all over to determine tank locations in order to replace the nonfunctioning sensors. Thanks for this tip.

That, my friend is a waste of time and money. Sensors generally do not work, are worthless if they do because they report wrong and should just left alone.


The fresh water is generally close. The grey tank can be left open when camping so no need to check it.


The black should be left closed and dumped when it "burps".


I cannot remember the last time I checked the sensor board on mine.

agreed. You will lose your mind if you count on these sensors.
