I use to lug 5 gallon collapsibles. Too much trouble to refill a 35 galllon tank. I just got a 55 gallon platic drum from a feed store and sterlized it. I bought a drill transfer pump- worthless junk. i'll return it today for this 115v 360gph portable transfer pump. I'll probably make a water tower out of another 55 gal drum and store some more on site.
