My most used tools in the RV:
- A screwdriver set with multiple drivers (including that square head one that seems to be every screw in the RV)
- A Leatherman Wingman multi-tool. Use this guy for anything that the screwdriver can't
I do carry a small toolbox in the back with some other stuff (rubber mallet, various pliers, voltmeter, sockets, hatchet, etc.). I rarely if ever crack that guy open when camping--unless I really really need that mallet.
