We decided to replace the MH with a smaller TT, we are done traveling so it is a better fit. We own our own camping spot on a local river so it will sit there most of the summer unless the river floods then it will come home. Got a portable waste tank I can bring home and dump in our septic system. I will need to fill the fresh water so I am looking for a 12 volt pump for that. Anyone have a setup that works well for them? Thanks in advance, Jim.

I bought a 40 gallon water bladder and a ShurFlo water pump. The pump is identical to the one that is in my TT. I put a male hose connector on both the pump inlet and the pump outlet. I also attached battery clamps and an ON/OFF switch to a long cord to the pump. All of that is in this plastic container. (Note that I DID fuse the power cord.)

I use a hose to fill the water bladder, and close it off with a hose end shut off valve. Then I drive to the TT and hook that same hose end up to the input side of the pump, and my regular "fill the water tank" hose to the pump outlet. I then hook the pump to the battery, turn on the switch, and it fills my 40 gallon water tank in minutes. No lifting water jugs.

I added a 3-port valve to the inlet of our onboard water pump that let's me draw water from portable water tanks to refill the onboard tank using the existing fill/use valve.

I thought modern RVs had a place to suck antifreeze out of jug, pump it thru systems. If you stuck that in a tank of fresh water would it know the difference?
Before go to refill portable tank use outside shower to MT into gravity fill.

Since we dry camp a lot with sites with remote water I came up with this solution.

a) mount a RV water pump in our pass through near the water inlet
b) wired the pump in with on/off switch
c) outlet tee into the fresh inlet line
d) inlet flexible tubing with SS dip tube

I use the blue 7 gallon water jugs, stick the dip tube into the weater jug, turn on the pump.

Works great and game me a reason to replace the noisy OEM TT water pump. Put a higher quality, quieter pump as the main pump and used the old OEM as the one in the pass through.

Doesn’t usually garner many responses. Maybe either because most of the rvnet contingent aren’t into water sports or maybe they think their home made setups are better. But a very easy simple setup is a wakeboat ballast bag or bags and ballast pump.
Quick high volume, durable and plug n play.
I used to use one of our bags when camping with the TC. If we needed to pack extra water in to the back country with the camper still on the truck (and kids in the back seat) I’d fill a 400lb bag on the back seat floor. Supplied hose with the pump and the cord were long enough to reach the cig lighter for power and the filler on the camper.
If camper unhooked, I’d put 800lbs of H2O sacks in the truck bed (or back seat) and bring in enough water to dry camp for a week like the water was free… Nice luxury for the wife to not have to take navy showers in the woods….
Just like other bladders they fold up small for storage. Bonus is you have a plug n play setup and you can get virtually any size/shape of bag you want vs the “bladders” which are typically flat and take up more floor space.
You can easily rig a pump and hoses etc to pump out of buckets, barrels, jugs etc as well.

Not cheap, but self contained portable. Milwaukee makes a battery operated pump.

There are many suitale transfer pumps.. I suggest the Bladder and Surflo. It's not that expensive. It is a known good pump and here is the real kicker.

Heaven forbid the on-board water pump in the RV fail..

IT IS A SPARE.
