In preparation for the Alaska trip this question has come up. This is something I would usually never do.

How long does water stay good anyway?
A gallon of water weighs 10 lbs, so my personal tank would weigh an extra 400 lbs if full.
That is what I meant. If you had to lift up that much water it would take a large amount of energy. To put that much weight into a vehicle rolling on bearings doesn't use much energy at all. People on this forum that have a toad generally report their gas mileage decreases about a half a mile per gallon when towing. A toad generally weighs 2000 to 3000 pounds. I have a 40 gallon water tank which would weight 350 pounds. My RV weighs 12,000 pounds. The extra weight will not have any affect on my gas mileage.COMer said:What Tom probably meant was that the extra weight matters so little that it is not a factor and cannot be measured. Around here we have a saying that we would use to answer the question. We live near Lake Erie and we tell people that if you went down to the shore and spit in the lake, that technically, the water level would go up but not enough to notice.
