Currently I have a 275 gallon water tank in my GMC Savana. Recently I have been really picking things apart to assist with saving gas money, and one thing was water. I am wondering what size tanks people are using, and also does anyone have a tank that they are using a garden hose off of? I use a pressure washer, but I saw a guy using a 100 gallon tank that had an electrical pump which feed to a garden house. With my steamer, areas that would typically require a pressure washer will not be a must have. I figured I would ask around. Less water and not needing to always use the pressure washer will mean less gas used and less wear on my pressure washers. :getdown
