I just got my first car and it's a little two wheel drive toyota pickup. I am gonna build a box in the back that will just be a giant waterproof drawer to hold my essentials because there's not much wiggle room in the cab. I have an area about 21 inches wide by 36 inches deep by about five inches tall that I can use for survival gear and stuff. I was wanting kind of a get home kit and an overnight gear kit hybrid. If that makes sense. I was wondering what u guys thought about it and what I should include in the box? Thanks for reading my post!
