Query: Cool if you can easily carry 50 lbs around!

A gallon of water weighs approx 8.33 lbs. 6 gallons = just a stich under 50 lbs. The dogs sleep upstairs and the water supplyis downstairs. I can not beleive other people don't have a problem with this. especially if you have to keep changing the water.
