As others have commented, too many variables. Bear in mind that there are lots of successful survival stories involving no "kits"at all, just the will to live and a resourceful mind.

If you are carrying everything with you, a realistic,practical limit for most of us is somewhere in the 40-45 lb range. Less is much better. Even then, there is an important variable - need for water. Are you in the Arizona desert or the Minnesota north woods?

One could go on and on.....
