I would defiantly recommended getting the largest tank possible. i have a 67 liter tank in my XJ and the range is roughly 200 miles so i am frequently at the pump. Previously i had a car with a 90 liter cylindrical tank and wish i had this in the XJ. I think you would be surprised at how many auto gas stations are about, i thought there was only one on my commute but once i started using an LPG car i found there was 3. I also have an app on my phone to help me find station in areas that im not familiar with.
