I would like to add GAS to the pre-run check list.
It seems like common sense, but still many people forget it. In flight training the importance of gas cannot be stressed enough. Just because you have a full tank doesn't mean you have enough. Sit down for a minute and figure out where gas is, and how far you are going to get before needing more. Also keep in mind not all stations or towns are 24 hour!
I think that should suffice... I don't think physically dipping your tank is necessary in your FJ, but it is common practice in aviation and we have had some fuel gauge troubles on this board... hmmm...
(okay... one more thing... you will use more gas offroad than on-road)
