I have looked around and not found anything else on the market that will do that this kit will do for you. I have a situation there I don't have room for a larger propane tank, but I do have room for three smaller tanks. One won't last long enough for my needs, but three are great. This kit allows you to daisy-chain one tank to another, and a second kit the third tank. You could add as many as you need, with one kit for each additional tank. They will all draw down at the same rate and be empty at the same time, so you can fill them all the same time and save a few trips to town. Or, you can turn on one tank at a time and draw from only that one if you wish. A good price at TSC too.

Quality product. Kit should include separate shut offs for each tank so you can swap tanks out one at a time without having to shut both tanks down.
