2016 Jayco WH 23MRB:
Where to find tank position, layout.
Thanks,

Maybe you could email jayco for a tank drawing.

Yes, email Jayco for the tank positions. I just did this and they sent the wiring, plumbing schematics that included all 3 tank positions. Have your VIN ready, they ask for it.

Crawl underneath and you’ll have your answer in less than 1 minute.

unless there is an enclosed underbelly

Enclosed underbelly......
Thanks for the replies, guess I need to call Jayco.

First I would look down the toilet and see if the tank is right below it and if it isn’t it should be very close to it and the grey one will be right next to it. Your clean out pipe should be between the two ( another give away). Your fresh water tank will be in front of that one and from the outside your low point drain line should be in line with the tank. I would also check at the rear of my cabinets for where the the grey lines join and drop down thru the floor ( another give away) for its location.

PaulB12, With an enclosed underbelly, I would start with contacting Jayco. Have your Vin number. Hard to say which set of schematics you will need, might need the frame structural drawings, maybe the plumbing schematic, both supply and waste.

It seems on newer rigs if the FW tank is between the frame rails, it is above the axles. If the tank is inside, it is under a bed, or dinette bench. Hard to say. Waste tanks, seem to most often be grouped together, with the black tank directly under the toilet. With the grey tank right next to it. But if you have multiple tanks, then the other tanks could be anywhere.

Your fresh water fill is ( as you know ) just to the left of your front door and that fill port is usually just above the fresh water tank that’s between the frame members. Look under your kitchen sink and you should see that water line ( or pipe) from the fill port going thru the floor and directly into the tank ( a sure sign it’s directly under under your feet if your looking at it), grey line from your sink is running to the right.

[PaulB12]

OK, that all makes sense.
Now do they run side to side or front to back. I'm trying to figure out how the weight would be distributed with varying levels of liquid.
I like to travel with as little of any if possible.
It's looking like the one I'd prefer midship is likely furthest aft, i.e. black water.
Again, thanksfor all the help.

If they are under the TT, between the frame rails, the tanks run from side to side.

If your FW tank is above the floor, it can be located anywhere. But you have a WH, so I am confident it is located under the floor and also run side to side.
