Needless to say, it's another of those easier said than done things. Inventory your stuff well in advance of the move, attend to secure packing of firearms, ammo, reloading supplies, optics, everything you intend to keep. Then figure out whether you can crate it all up, purchase or build a suitably secure outer container that you can lock in a manner that would cost thieves a lot of time to break into. Then decide whether your truck or trailer will be practical for the haul or will you need to rent something larger. If you'll be hauling a heavy safe you'll need to get a commercial-grade truck. Along the way, stay with your stuff or real close. You can always replace a household appliance or a piece of furniture, but not your shooting-related property. Add the wife's jewelry & keepsakes to your stuff and she'll sleep better. You'll probably succeed getting moved vis-a-vis thieves. But depending on where you go, cops could be a different story. Just try to comply with the traffic laws. Good luck.
