As many have said the CB radio which requires no licensing but is very limited in distance and clarity is obsolete now for trail use especially now that GMRS has evolved with higher power mobile units and repeater channels which also requires a FCC license that involves no test just fill in form and pay fee and it’s good for you and your household.
Ham is a great option to keep in your rig also since it’s been in use a very long time, can be used for simplex short range or farther by jumping on a repeater frequency which is very accessible now with tone coding for the repeats online or in guidebooks. Ham license now days can be done online by taking the test and paying the fee but a ham license can only be used by you alone. Additional if you want to reach even farther distances you can get a higher FCC level ham license and go explore ham HF stuff.
Personally I also have all of the above except HF. I mainly use on daily basis or trail my gmrs or ham units. My CB is just there in case as a backup.
