Need 4-post lift capacity recommendation

I bought a 4-post recently. The biggest thing I have to put on it is my 2500 Ram TCD. It weighs about 5800 lbs dry, so I figured a couple of hundred more for fluids and the tools in the back. Then I got an 8000 lb lift as I wanted a little extra capacity. I would not want to lift one ton of weight with a one-ton jack but that's just me. Your owner's manual will give you the curb weight on your vehicles, or you can take them to a truck stop and for a few bucks they will weigh them for you.
