Increasing potable water tank

My camper has a 55 gal. fresh water tank (I think). I purchased it used in May and took it out for the first time on July 23rd. We ran out of water in 3-4 days and refilling with a water jug was a pain. I have an extra 45 gal. tank laying around and I'd like to install it beside the original (under the bed. Yes, there's room).

Anyone see a problem with simply teeing into the fill, vent and pump supply hoses or is there a better way I'm not thinking of?

    ScottG - If using the tee, wouldn't both tanks equalize and empty at the same rate?

    2oldman - Lots of great ideas there. I also happen to have an old water pump that I'm pretty sure still works. I could wire the pump to a 4 way flat trailer plug, fill the tank in the back of the truck and pump it off into the trailer.

    dennis1 - Not sure what your talking about here. NF CG? We already use paper plates and bowls and use the campgrounds showers and, as often as possible, their toilets. We try to conserve as much as possible.

    If you just use a Tee at the supply line, the pump is going to suck air from what ever tank empty's first. I would install a selector valve so you can chose between tanks.

    I keep a 12 volt battery charged for trips, and what I would do is see about using a food-safe 50 gallon bladder tank, using house water pressure to fill it, and to empty it into the RV, using a 12 volt water pump.

    As a single person, the 51 gallon FW tank on my TT is enough to not be a bottleneck. My grey/black tanks end up full before I have an empty FW tank.

    I have a 15-gallon plastic barrel laying on an inverted pallet in the truck bed. I fill it at the cg faucet, drive to the TT, and drain it into the FW tank. The old HTT was low enough to get a siphon feed going, but the new TT is higher and I'll need to come up with a pump of some sort. Emptying it into a 6-gallon jug and lifting it to fill the TT got old in a hurry last weekend.

    Are you camping in a NF CG? I use an A-dapter. Connect the plastic adapter to the facet, hose clamp it and connect a hose to the threaded adapter to it and fill the take up. Works great. Other option is use less water, shorter showers, washing less dishes, use paper plates. I think 3-4 days is quite long. We use up 45 gallons in 2 days.
