Not an OTR driver/trucker, but I usually carry a basic AM/SSB CB and a 2 meter simplex radio in the vehicle when traveling the interstate highway system. Will run both simultaneously, CB Ch19 and ham 146.52 simplex if the vehicle has two antenna mounts, otherwise one or the other depending on weather/mood. CB for bad weather for staying alert to road conditions. Sometimes if I get super bored I'll work skip on 38 LSB, but operating a clarifier while driving is a pain.
For something in the vehicle for local travel (< 500 mi) I find myself more and more gravitating to the GMRS linked UHF repeater system here in the Albuquerque/Tucson corridor. https://swcrs.org/ and system map attached. It's a bunch of GMRS repeaters using wideband deviation that are linked with AllStarLink technology, but it's a sparate network from the ham VHF/UHF AllStarLink system. I'd say half the users are CBers who got a GMRS callsign, and the other half are hams who got a GMRS callsign. If the FCC lowers (has lowered?) the license fee from $70 to $35 there will likely be more people moving over.
Anyway, if you have a linked GMRS system in your area, give it a try. UHF linked repeaters may be where things are headed. I understand they've been the thing in Australia for a long time.
Thank you for the picture of use you provided.
