Why don't you just put a threaded end on a interior faucet, and pass a hose through the window?

Just put a threaded 3/4" connection on low point drain.......hook up hose, turn on pump open low point drain valve and wash away.

Thanks for all the great ideas everyone! Another reason I thought having a pump on the tank on the truck would be for possible help if a small fire were to break out.

A normal RV water pump can take water from 4' below the pump location. It helps if the pump and tank water level are close while the pump is taking in air, and getting primed, but it is not a requirement to have the pump below the water level while pumping, because it is a diaphram pump, and can take in negative water pressure up to about 10' of suction depth.

So I would get a normal 12 volt RV pump, attach a 10' hose to both ends and pump the water either into the fresh water tank in the RV or into the fresh water inlet. You can even get really clever and mount a additional tank on the RV roof, then fill it with the pump, and have a valve going to the fresh water tank, letting it gravity fill as you need it. In theory, you could fill the 55 gallon tank 3 days a week, and fill the fresh water tanks in the RV (including a new roof one) only a few days per month, saving time.

RJsfishin, how much would that waterboy cost? It looks interesting. I can't find any info on that site. Tahnks.

If you already have a good size 12v to 120v inverter in your trailer I would go for a 120 volt water pump, many pump options at a good price. That way you can use regular extension cords and go much longer distances if needed, 12volt dc wire runs need to be fairly short.

I have a pump and setup for pulling water out of a stream or lake and decided to go 120 volt.

Have seen several set ups like this over the years.. You have two choices in the 12 volt pump.

1: Standard RV pump.. Advantage this method... If your main RV pump ever conks out on you you can pirate the barrel's pump as a spare till you get to town for a new one.

2; Harbor Freight has some 12 volt pumps as I recall.

3: use a 120 volt pump (Small one) many sources.

I have that setup to pump water into my fresh water tank from 5 gallon jerry cans while boondocking (2 cans, 4 trips fills the tank). Works like a champ.

Side benefit, if the pump in the RV ever dies, I have a spare on board already since the pump I use is the same one that was installed OEM.

I have a Nomad Portable 12v pressure washer.. works great, uses less water and good pressure
check it out Nomad website

They sell those barrel pump assys here in Quartzsite.

I myself use this,...works good
