three things,
1: if you get or build a trailer, you might want to have a spare fuel tank as an integral part of the trailer.
2: look into a small photovoltaic unit to trickle charge your battery or any other electronics while it is parked (in the sun)
3: go to the junkyard and pull an electric fuel pump that works, wire it up so that you can plug it into your acc outlet. make sure you put a 3 position switch in the wire (on, off, momentary). Make sure you have plenty of hose so if need be you can pump right out of a gass stations storage tanks.
