toilet paper... never forget the s@#t tickets.......
ha ha , thats the one item you dont want to be without ...
if you dont have get a fullsize spare and a cb radio ...
I usually pack a few basic things like the following that fit in a small rubbermaid - my space is ltd, whatever you pack make sure its tied down with seatbelts or bungee cords cause it can hurt you or someone if things get rough ...
- camera
- antifreeze
- ltr oil
- spare fan/alt belts
- work gloves for spooling winch
- winch accessories
- few multi use tools like vice grips, few sockets, hammer, smaller pry bar ...
- lotsa water (mostly for me)
- duct tape and extra roll of wipe
- map(s)
- garbage bag to haul trash out
am sure others can expand on this ...
