Keep in mind too those kind of things you probably might never do on the road. However, I do keep the tools needed for changing out a headlight or a tail light, tightening cabinet screws, opening up panels, etc.
You should carry spare bulbs, fuses, etc. Duct tape mostly for comfort. With my old 2005 Sprinter I did carry a spare turbo resonator and the tools needed to change it out and never had to. Other than that, I have never carried many spare parts figuring I would buy them if needed.
