Expanding fresh water capacity.

Wondering what others do to expand their fresh water capacity. One of our favorite campgrounds has many site with electric only. We have a 314BDS and 5 people so our freshwater lasts us about a day to day-and-a-half.
Can we add second tank for more capacity? How about adding a larger tank altogether. We never tow with the tank filled, always fill at campground so weight is not a real issue.
Thanks in advance.

When I was a kid my dad bought a 30 gallon water tank and installed in under one of the bench seats in the dining area. The only drag was he had to run a hose to the other side to fill it.
(good ppl there)

If you look in mods you'll see what I do--- I just carry a 30 gal barrel and a 110Volt water pump. That way I have a unlimited amount of water. Only drag is I still have to dump the gray water once a week.

Excellent. That is what I've been looking for. Great idea with the pump. Bi wouldn't have thought about a pump. Went on first trip, filled the accessorie tank and then been.......huh? How am I going to lift and pour that into my fresh tank
Only other thought was buying a couple hundred more feet of hose

Lots of people carry a plastic barrel or a water bladder. If there is water near by you can just fill them when needed.

I was born with nothing and I still have most of it left.
