yup 85-100 that's it, I usually go through about 18-19 gallons per bigger storm like over 10" I don't consider a tank of gas per storm anything to lose sleep over either, I sleep very well, for 6-10 hours every night. my truck has two tanks and between the two of them I have put 40 gallons in total, but i really have to run them down far to fit that much in there, so in the winter i only fit 19 in the front tank and usually 16 in the smaller rear tank. I drive around in 2wd whenever possible. plus i never shut my truck off until i'm completely done with my route and at my house meaning it will idle for a few hours during my route. so that doesn't help my fuel economy but its fine how it is really.
