Carpet!

I have one of the Contico boxes from Walmart with tools, jumper cables, a drop light, recovery gear in it, 50 rounds of my favorite ammo, AR-15, etc.

My Lobo shelf has all sorts of creature comfort stuff, MRE's, blankets, add'l first aid kit, trekking poles, 2 way radios...

Basically enough to stay alive for 3-5 days if SHTF, and handle most minor to medium vehicle problems.

Oh yea... there's duct tape and bailing wire as well.

edit: When clicking this thread, I was fully expecting photos of a large woman's posterior.
