Yes.
I keep one in my RV at all times for 'safety' reasons.
I use a Cobra HH ROADTRIP Handheld 40-Channel CB Radio
It is on the dash with the "squelch turned down". And turn it up when needed. It comes with mag mount antenna but I have never had to use it. IMHO I think all RV'ers should have one for the safety of themselves and family.
1. For getting 'real time' 'right there' info on road conditions/accidents. GPS can not do that.
2. As an 'additional' form for emergency contact, i.e. if something happens and I don't have cell phone coverage.
3. This CB also has real time 'where you are at' NOAA weather alert.
It has already paid for itself:
Once when a car came over the median way ahead of me and crashed head on with a semi. Turned it up and got instant real time information what lane to get it to get around or otherwise be stuck for there for hours.
And when I was unknowingly driving right into where a tornado was coming down. CB NOAA weather alert went off on CB. Got off at next exit. Saved my life.
