Seems to me the power supply in the truck is your best bet. The router probably runs on DC at relatively low power compared to something like a car stereo, and the truck's battery would make as good an all-weather UPS as anything I can think of.
I don't have any direct experience running wireless in a truck, but I do frequently run a motorised telescope from a car battery in remote locations. I would advise against running anything directly from the truck's battery in case you over-discharge it and are unable to start the engine again.
Either use a deep-cycle leisure battery (which can be charged from the engine when running, but kept separate from the main vehicle battery when discharging) or if you really want to run off the main battery, include some electronics that will prevent over-discharge.
You can find these kind of systems in motorhomes - perhaps ask a motorhome service centre about getting this kind of circuit put into your truck.
