I got a CB for easy convenience, cost and prior knowledge. Longer term the plan is to get my license and go 2 meter to start and then see where that goes. Since the radio will be used most on the trail and most often when rigs are in eye shot of each other, go with a 40 channel handheld CD and forget the antenna. I got a Midland that can be either handheld or truck based with external antenna but I suspect in 95% of the uses, the handheld configuration will work just find.
On a side and humorous note, back in the late 70's I had a Cobra 29 (no 40 channels then) in my Dodge Power Wagon and listening to the truckers on 19 then and now, it sounds like time just stood still.
