Note to self, don't use the auto suggestions for names..... sorry Brent.
As for why truckers have migrated to GMRS, the stated reason is better audio quality being FM rather than CB's AM, antennas generally come pre-tuned, and slightly better range.
The unstated reason, since the late 70's four wheelers were getting on the CB and messing things up for the drivers. So they switched to get away from them and the reasons stated above. Besides a license is just $35 and there's no test.
