On the subject of a 300 gallon fill up... that only needs to be a one time thing, even then, when you acquire such a rig it may already have a decent quantity already on board. After that you simply add fuel just like driving a PU. There's no rush to top off the tank if it's low either. The pro is you can pick and choose where you fill up the 20-30 gallons you used to drive 300 miles you drove or pocket it and buy 40-60 gallons later at better price. With 300 gallons on board you can afford to wait and get the best fuel price. Rarely should you ever drain the tank between fill ups. Money Management 101. Everybody is getting freaked out by a 300 gallon fill up... If you run that way then yeah, you will have some big, but infrequent, fuel bills.
