I want to lift water about 20 feet from my truck to the storage tank on the
second floor of my cabin.

I used to be a commercial diver, and have used many types of "airlifts."
This is a device where a suction is created by venturi-ing air into a line
in the direction you want it to flow. In real underwater conditions, the
air expands as it rises, increasing the suction power. It really sucks up
whatever is in front of the nozzle.

I was playing with the idea of buying a pump that I could pump water from
my truck tank up to the storage tank of the cabin. (This is just for
winter use. In the warm months, there is a water system.) I am running
into the problem that a lot of them just don't have a lot of head
pressure. And they cost a lot. And they require special plumbing
connectors. A small compressor would not have to put out a lot of air to
lift the water in a 1/2" line and get it to rise up. The bubbles will
push the water up and rise automatically.

Anyone else ever done this? Venturiing is a good way to make suction
devices for all manner of applications, and they are really safe because
they just use air or water.

Seems like the hard way to me.
I think it will cost more to do as you propose than you can buy a pump for!

may be a tad short on lift.

How much are you willing to pay?
