1. Keep things ship-shape. Everything in its place, every time. When you stop for gas, check the oil, diesel exhaust fluid, empty your trash, and clean the windshield—because at the next stop, it might be cold or raining. My dog food stash is near the dog medicines, which are near dog bowls, which are near the dog crates. The guns are located near the gun oil, which is near the ammo. Shooting glasses, license, whistle, and gloves are stowed in my hunting vest.
