I have both a CB and a quad band ham radio in my Cruiser. That said, if I was going to only get one radio it would be a ham radio.
Consider this email as just information for any of you who might be interested in ham radio. I have an Amateur Extra license, however, the minimum license that is required to operate a ham radio is Technician--which is extremely easy to get. Usually, when you say the words "ham radio" one has the image of some very nerdy/geeky guy with lots of crazy radio and electronic equipment, and yes the ham world does have some of those folks. Having said that, there are a lot of folks who look at the world we live in and think I really need a way to communicate in remote areas or in an emergency. Also, the trend in recent years, in the off-road/overland community, has been to move away from using CBs and move towards using ham radio. At one time becoming a ham was not so easy. A lot of hams built their own radios, had to learn Morse code, etc. Becoming a ham these days couldn't be easier. The entry level to the ham world (and probably all you will ever need) is the Technician license and Morse coded is no longer a requirement.
I highly recommend you get your ham Technician license if you haven't already done so. It is super easy to do. You can pick up an inexpensive Baofeng UV-5R radio (5 watts) which cost around $30.00, the Ham Test Online (https://www.hamradiolicenseexam.com/) course cost only $24.95 and taking the 35 question Technician exam is only $15. So, basically, for less than $100 and about ten hours of your time (for study) you can be ready to go. Too easy and inexpensive not to do it! Baofeng has just released another radio, the F8HP (8 watts). Both radios listed above are great radios, especially, for the price. If you are into survival preps (as well as off-road) you should consider getting a ham radio and getting your Technician license.
There are also additional antenna upgrades you can get for the Baofeng, i.e. a 16 inch antenna to replace the “rubber duck” antenna, a vehicle mount antenna, as well as a Slim Jim J-pole antenna for your base camp. Later on you may want to pick up a 50 watt 2 meter radio for your vehicle in order to increase your range.
For what it’s worth the overland community has an unofficial “official” overland frequency which is 146.460. If you have any questions send me an email and I'll see what I can do to help.
