You are wise to be careful. I moved out of Colorado a few months ago, but I can say there is a ton of theft that happens during hunting season. Most of it is in the more developed parts of the state. Having Kuiu and Sitka stickers all over your truck just draws attention to it, so that doesn’t help. Standard truck topper locks are easily popped. I prefer to sleep in the bed of my truck (I built a bed into the back), so that makes it tougher for anyone to steal out of it. Use common sense, pay attention to where you park, lock your stuff up as much as you can, and don’t display your goods for the world to see.
