I am contemplating making a UDS out of a 120 gallon propane tank if I can find one affordable enough. Can anyone tell me how much one of those weighs empty? I still want to be able to lift it in the back of a truck to take places like I currently do for tailgating parties ect. I know it will weigh a bit more than a barrel but how much we talking? I am seeing reports on google searches saying those things are over 200 lbs. Yikes!
