The one other thing you may want to check is the law on possessing a handgun in MN. The federal law only protects you for uninterrupted travel from one place where you can legally possess to another place where you can legally possess. If you can't legally possess the handgun in MN because your not a resident and you stop for more than what it takes to refuel or get something to eat, you are putting yourself in legal jeopardy. For example, I'll use NY since I used to live in NY and am familiar with their laws, I now live in Texas and have a CHL here. If I were to travel to VT where I could again legally possess and carry I could use the lockbox to secure the gun in my trunk unloaded with the ammo and be safe. As long as I didn't stop for more than a refuel or to get something to eat. If I were to stop to visit family or spend the night I would be breaking the law since you can't even own or possess a handgun in NY without first getting a permit.
