Step 1: Obtain your propane tanks.

I bought one 250 gallon tank and one 50 gallon tank from Taylor Gas, a propane dealer south of the city. They're 20 years old, rusted, but plenty usable for a barbecue. The metal's around a quarter inch thick.

You have to flush out the remaining propane when you get these things. There's going to be some, not a whole lot. But the way to do it is to fill the tank with water and let it sit for a couple months. The tiny propane bubbles on the side of the tank will work their way out.

So when I got these tanks, they had fittings all over, remnants of their original purpose which were no longer necessary. I used a pipe wrench to pull as many as I could, and then broke out the Saws-All to clip off the top of the big tank. It took about 40 minutes to fill the big tank with 250 gallons of water.

Now, they sit for a month or two, while we get the parts for the trailer.
