Generally speaking I carry more than I'll ever need in my many emergency kits-but I always say having is always better than not having when you need something! Well, as discussed here before, just replaced my old Spot2 with a Spot X. I carry all the usual getting "Unstuck Stuff" like handyman, jerk and pull ropes and heavy duty jack, come-along, shovels, axe and fire type and wood cutting tools! A good tool box(s) for fixing just about everything on the camper or truck. A couple of first aid kits that I update yearly-nothing worse than needing something and discovering it is out of date or will not stick to your skin when you need it. Several rolls of duck tape and. a couple of tarps. Lots of different types of ropes and a box of thing-a -ma -witch -a- mah -call-its, left over from old fix it kits!
Okay, some new additions this year; one of those $ stand alone battery starter kits; they don't take up much space and I just hook it up if my battery goes dead on me! I bought one of those prepackaged week long emergency food kits and a new type of water purification kit and some bottles of ready hour survival shot for that vitamin/mineral extra---still looking for a trailer to carry it all, so me and the dog have a place to sleep at night 
! Over the years you do learn though what is really needed, it just takes time, old age, and getting stuck allot before you do!
