Depends on the journey. We keep a first aid kit, flares in ours at all times as well as our tire pump and air down kit, but we also have recovery gear like 20k lb straps, d-hooks, etc if we are trailing. So I guess it all depends on what you are looking to do and have. The spare tire in my eyes is useless so we have a full size spare we are going to be using on our rack to take with us all the time with a rim to match. We also have a GMRS radio for emergencies in the event we don't have cell coverage.What products does every have or want to get for your roadside emergency kit? Or items you always have in the car for spills, clean-up or other reason?
