I have a lot of windshield time, I used to run all 6m, 2m, 70cm. I've pulled them all out and only run CB and 2M
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.
I'm not sure that MURS with a 2 watt limit on VHF and FM modulation has much utility. There aren't a lot of "type accepted" or "certificated" MURS mobile radios; Wouxun MURS mobile radios like the KG-1000M are selling for north of $300. The northwest Canadian LADD VHF frequencies would be the prototype for trucking, those are required to be licensed and are 30 watts. So not sure what to do with an unlicensed 2 watt VHF radio in the mobile environment. $300 is a lot of coin for a 2 watt radio. I run a $140 2 meter rig at 35 watts typically on 146.52 simplex, can boost to 80 watts to complete a conversation if range gets spotty. The idea behind MURS was to legalize the practice of people taking their VHF "colored dot" business band HT radios from the construction site to weekend hunting trips, Walmart giving every floor employee a VHF handheld, etc. The intent was not to create a new unlicensed mobile radio service for trucking. The Alaska Trucking Association had to get a FCC license for 12 channels of VHF at reasonable power (up to 75 watts) for use up there, similar to LADD. But again the Alaska service is Part90, not an unlicensed Part95 service like CB or MURS or FRS.
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 separate 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.
