I camp often in the Sierras and recently upgraded my experience with a Dometic Fridge that I plan to keep in the back of my Gladiator when going dispersed camping. I am contemplating the best practice with the fridge at night when we are getting ready to sleep. Keep it in the bed of the truck or bring it inside the cab? A bit concerned that either is not the perfect bear-proof option and brown bears in the Sierras certainly have experience breaking into vehicles. Thoughts or experiences? Thanks!
