Thank you for all the advise guys.
CB wasn't going to be my main radio since I am a HAM. I wanted to have the CB in order to talk to truckers along the highway and get a better road condition reports etc.
Last week we decided to buy a small motorhome at a dealership in Arkansas. We rented a car and drove there from CA and once we got the RV we drove it back to home in CA. about 4500 miles in 5 days. At some point along the route there and back weather got a little bit scary and at those moments I wish I could've talk to oncoming truckers to find out how was the conditions where they are coming from.
Otherwise my hobby activity is HAM radio. But I did not know about truckers using GMRS nowadays! That's good to know. CB technology is sooo ancient nowadays but I thought if that's the only way to contact maximum number of truckers along the routes, so be it!
I'll continue to investigate.
