I bought a hand held CB when I went full time. Figured it would add to my ICE as a last resort if no cell phone towers in case of an emergency.
The one I bought has a real time NOAA weather radio which saved me many times from driving blindly into a tornado.
For backed up traffic it gives you 'real' people in 'real time', actually there at the scene, to report the hows and whys and where to get off when RV'ing where you didn't know the area.
No holes to drill, no antenna to mount. It came with a magnetic antenna you could just put out the window and up on the roof but never had to use it to get reception.
It rode in the MH laying on the dash board, squelch turned down.
IMHO one of the best things I purchased for the MH.
It's called the
Cobra Road Trip 40-channel CB.
