I would recommend a ratcheting screwdriver with interchangeable bits such as this Gearwrench
With a smartly chosen variety of bits, you will have about any potential screw driver need covered by carrying only one screwdriver instead of many. This can be important for a small tool bag kept in the truck or camper.
And make sure you get decent stuff and not cheap crap. Being 100 miles from the nearest town is not the time to be kicking yourself because your cheap assed tool did not work or it broke the first time you tried to use it.

Just kidding, that's part of my tool box at work.
