Hmmm, mister macho huh lol. I am on the wieght lifting squad at my base. I can deadlift around 650, and so can several on our squad. When I moved my pond that is in an insulated plywood box we estimated the weight around 1000 lbs. Thought no problem for four of us. We were wrong lol. We could pick it up, but moving it was a different story. We called in 4 more buddies. Total of 8 of us beefy military guys carried it a total of 20 ft in about as many minutes. Can you say akward? I think that it weighed more than we thought, but just think it was made of wood. 7ft x 7ft x 2ft. Can't imagine what the metal will weigh. You will need thicker metal than what you are thinking. For cost, and reliability I would go plywood for your dimensions. The tank will still be heavy as hell lol.
