I've used the Motorola Talkabouts in caravans to/from the tracks and some large BMW meets and on the mountains while snowboarding. They work great in the car but the actual range is about 1/2 mile on the road, less if it's hilly. This is with the really old talkabouts that first came out. I've since bought a set of 5950 which seem better but I haven't used them enough but they do seem better than the 1st gen radios.
I've been thinking about installing a cb radio in the 4Runner. That among a few hundred other things
