In the late 90's, I had a CB installed and liked listening to the chatter as we went along and listened for info from the truckers. Then we stopped RV'ing for 6 years and when I set up the RT 210 in 2005, I installed a CB again and used an bent steel mount on one of the front fender bolts near the Radio antenna on the cab-portion. By 2005, the CB world had changed dramatically. Not much info anymore, no one monitoring the RV channel #13, and more profanity than I care to remember. Sorry, I would not bother installing one again. We carry a Cingular Cell phone and have been able to get out from almost everywhere except some of the remote areas. Truckers are all satellite and Cellphones now. I'm not to sure how they talk as they go now.
We also carry the laptop now and check for access when we go. A good place to get free access is in the parking lot of most public libraries and most towns have one and they usually have a free parking lot.
