We stopped using our CB years ago after cell phones became so popular. I'm hard of hearing and the small speaker in the cb was almost impossible for me to understand what was being said and more often than not, I had no idea what was being said. However, with a good cell phone and bluetooth capability on the MH's radio system, I can converse quite easily.
As for the cb providing traffic updates, my GPS navigation system does that quite well...I'm always surprised when it comes on out of the blue informing me that there is a detour 5 miles ahead, or that there is a traffic slow down due to an accident in the left lane, or....
We do have small hand held radios (does this count as a cb) that we use when backing into a site.
My cb is setting on a shelf in my garage....
