Under truck water storage

Has anyone on the forum installed a grey water, or fresh, at the rear of the where the spare tire carrier is? Since we don't have a gray water tank and are moving the spare up front this is vacant space.

Our last TC had smaller tanks...I put a blue boy on the rear hitch haul for our x-country trips.
This doubled our tank capacity and worked very well; when the on board tank was full, I would dump into the blue boy. When both the bb and on board tanks were full...it was time to find a dump station. I drilled through the bb and installed a hose fitting and gasket to allow dumping.
No reason you couldn't do same...

That would be an interesting project and very doable . Cab/Chassis trucks have their second fuel tank in that location . You would have to have some sort of disconnect between the tank and camper so the camper could be removed from the truck without the tank . Perhaps a heavy duty slinky hose with standard RV connectors . Here is a company that makes a ton of different sizes and shapes of holding tanks .

If you found one with a center hole you might even be able to use the tire lift system to raise and lower , just thinking out loud .

Ours is plumbed from kitchen sink, bathroom sink and shower pan down to just below the 3" black water knife valve between it and the cap. It's possible to reroute the last part of the grey water drain from that location back under the truck to a tank installed where the spare tire usually is. At least that's my dream. Then have an independent grey water valve and cap and seperate black water valve and cap with no connection between them like now. The drain from the grey tank could be simply a water hose as I put NOTHING down those drains but soap and water. Dishes get wiped down before washing. Really need to get the front receiver hitch installed then see what I've got under there in the back to work with. I must not have enough to do that I need to look for more "entertainment". Crazy old lady. Typical TC mentality maybe. Seems like most of us keep looking for something else to do to our rigs.

What is the source of this grey water? Kitchen sink?
I've seen where someone mounted a PVC pipe, running front to back along the outer edge of the wing. Capped at one end with a drain at the other.
I hope that makes sense.

We don't usually camp in freezing temps, dump tank as we leave camp anyway and don't usually stay one place more than a couple nights at most so freezing isn't a problem. It's for grey water rather than fresh also. Our old camper wasn't built with one, just black water in wet bath. 25 years ago sink and shower water wasn't a big issue I guess. Once we get the spare moved I'll have a better idea of the space and configuration I have to deal with. Could just build a box and put a bladder type tank in there. Incoming and outflow drains and such another thing. Flexible and removable flexible hose from camper needed when we remove camper from truck if we ever have to. Sorry, I tend to over think things. My son does have a good sized sheet of 1/4" aluminum just stacked out in back. .....hmmmm. Another trip to the welder and to think I just told him I was done remodeling! Poor guy. I've taxed his imagination a lot in the last year but he's always been up to the task. So far.

You could fabricate a holding rack for a tank and plumb it for warm weather use, otherwise you'll need to insulated it and possibly heat it using a 12 volt mat or heat duct.

Watch your rear weight as to NOT overload your rear tires. ;)
