Nick,

How about this for the passenger seat. I don't have one but it may do the trick.

That is interesting. I've seen this before but haven't used it:

As for the extra fuel....
the aux fuel cell is the way to go if you really want to extend the range. If you stop to put in the extra gallon or two you're carrying, you may as well have stopped to top off the tank. That being said, there are only a few places in this country where you can't find gas for over 130 miles.
To address concerns about it being a "bomb", it's about the same as the "bomb" you're already sitting with between your kneesimage
