Most of my camping gear is in the garage too, I built a row of shelves one year so I could clean up my garage. All the tools sit on one shelf, then oil and filters and such on another and the camping gear on the top. If I actually did need to evac then its a simple matter of tossing everything from the shelf in the back of the truck and going, the organization is such that the gear is stored pre-staged and ready to go.
