My wife and I and her sister and sister-in-law are driving to Mississippi, leaving the first week of October. We will be pulling our travel trailer and the sisters-in-law will be following in their camper van. We will have GMRS radios for comms between us and of course cell phones. This will be a three week trip coming back through Santa Fe, New Mexico, then back home to South East Arizona. I'm looking for help deciding wether I should also use a Cobra hand held CB with a magnetic roof mount for help in case of accidents or bad traffic on the hwy. I was thinking it might come in handy especially since we will be traveling through the south Dallas/Fort Worth area. It's something that I could probably use in my TJR also. I'm an old part time trucker and know the limits of CB, and I really don't want to install a mobile unit in either of my vehicles.
