All that equipment sounds like you're [sp] driving to the north pole and are planning on homesteading if you have a problem. Any kits that don't weigh a thousand pounds, force you to take out the back seat, drag a trailer and/or take out a second mortgage to buy?
Edited for spelling.
In Florida perhaps you could survive with a Speedo, sunscreen, bug spray and bottled water.
I recommend storing it all in a zip-lock bag, and including a garbage bag in case the wind comes up or you encounter an impressionable Girl Scout troop.
You should also have in your kit a knife to slay the reptiles. And a cheap prybar.
The cost should be minimal and you could still curl up on your backseat.
