Water tanker?

Hey guys...was wondering if anyone had put additional tanks on their tow vehicle to supply their 5th wheel with?
Gas and Diesel tanks are pretty self explanatory.
But what about water?
Has anyone added a water tank to their rig to bring water from town to their camp? If so...what pump do you use to get it into your system?
Any direction most appreciated!

OK if you can handle the extra weight in the tow vehicle .

BUT!!! The holding tanks are usually sized to handle one tank of fresh water .
(100 gal fresh = 60 grey+ 40 black). If your adding more fresh you HAVE to drain your tanks , somehow ; and most RV's don't have the CCC to handle all three tanks full, when being towed.

Something along the lines of a bladder might do the trick but you still have the waste water issue to contend with, as Skip pointed out.

In my rigs case, the fresh water tank is behind the axle and waste tanks (3) are forward of the axles so my pin weight is lighter when I arrive vs when i leave.

I bought a couple 35 gal poly tanks from tractor supply that fit behind my 5th wheel and ride well below the trailer. I used 3/4" nipples and 3/4" ball valves for drains. I can use a macerator to drain/pump waste into one of the tanks (which I painted on) and fill the other at the dump with fresh. I changed the fresh pump out on the trailer as it didn't hold pressure due to leaking diaphragm and run a short hose to it. Then I hook another hose up with a filter and pump it into the fresh tank. We can boondock a long time without hooking up the trailer and dragging it to the dump. When not being used they are stored under the trailer. I do use a tarp strap across each when we are pulling the trailer so they don't lift due to airflow and bounce up to hit the overhang. Tanks are $99.00 each.
