Without actually weighing it, I can't give you an exact number, but it's very light, as in my wife could easily pick it up by herself. The casters are 2" locking swivelers from Home Depot -- not particularly strong, but strong enough. Truth be told, I haven't rolled it very far fully loaded with kegs and ice, and I'm not sure the handles would withstand carrying it far fully loaded either. I sometimes load the kegs into it while traveling, but so far I've always carried in the kegs and the "kegerator" (for lack of a better word) separately, put it where it will stay for a while, and then loaded the kegs, ice, and CO2. The casters help to move it slightly as I open to reload ice, or line up a pan or something to drain it, but they definitely don't go off-roading or carry the keg across large uneven surfaces.
