Since we will probably have this RV forever I would like to increase the gray water holding capacity and the freshwater.
Not a whole lot of cry camping if you shower every day and so forth with only 60 gal capacity and 100 gal fresh water.
It's on a Freightliner chasis.
Has anyone installed larger tanks or more tanks???
Never done it, but remember water is 8 pounds a gallon. That 100 gallon tank is 800 pounds when full. Probably wouldn't hurt to add some capacity, but another big tank will add a lot of weight. I would guess it would not be too difficult to add a tank assuming you had someplace to put it that could handle the weight. You would just have to then run plumbing from that location, but that shouldn't be too difficult.

I was thinking the same thing.. We camp at Talladega and fill up with water at the bath house close to the campground so I was thinking the fresh tank is under the bed but only 1/2 way towards the very rear of rv so if I replace it with a larger tank to use up all the under bed space that would give me plenty of fresh water for the week at Talladega... now the gray water will be a different story ...
Never do anything you wouldn't want to explain to the Paramedics...
Agree with BigSkyBob: Transfer gray to black by putting a transfer hose or valve from one to the other, open gray, then black and cut off black when transfer slows. I do it all the time, with some minor conservation, it buys you a couple days on the same freshwater amount and we shower every day.

There is a knife valve that twists onto the pipe for your stinky slinky. You then twist on your stinky slinky. Close that valve and open the gray valve and then the black valve and the gray water will seek its level in the black tank. Then shut the valves. Do this a couple time during your stay and your can get nearly full capacity of both tanks.

Most of the places I dry camped, the plants where very happy to have a little water. I would dig a hole about 12" deep, fill it at night, then bury it so that mosquitoes did not find the water source. However this is not acceptable at places like Yosemite, and you must save the water for proper disposal sometimes.
Or do the dishes in a dishpan, and dispose of that in a nearby sink,or whatever is acceptable to the tent campers (toss onto grass?). Use the same dishpan to empty my tub/shower after I finish my shower, and put that water into my larger than normal 59 gallon black water tank, or use a gallon of the shower water for flushing at night.
SOme have gone so far as to hook up some sort of 12 volt water pump with the inlet at the grey water tank, outlet to the black water tank, or pump into the rinse port.
You can find larger tanks here. Tank-Depot.com I would recommend installing a second fresh water tank, separate pump too, then if one pump fails, you can run the other, or you can use both pumps while taking a high volume shower, if you have excess water to spare. Or turn on the second pump, open the fresh water fill to the tank, and pump the second tank's worth of water into the main tank, then you can shut off the second pump.
I would find a place to hang the tank under the frame of the RV, and use unistrut with 3/8" allthread to hold it up. It is good for well over 1,100 pounds. If the tank is large, then probably would use 3/4" thick plywood between the tank and the unistrut, to distribute the weight across more plastic, so it will not crack near the supports.
