On one of the trucking forums I'm on, there are several guys on there with HAM setup's, all are owner operators, as companies are really cracking down any more on some of these setups, especially the sketchy wiring jobs. Friend went to work recently for a company that doesn't have inverters in the trucks, he asked to install one they said no, when he talked to the shop about it, they said the company had lost 3 or 4 trucks in recent years to improperly installed inverters, so now they were prohibited. The shop was required to inspect all trucks for inverters or add-on wiring during PM's, then photograph, report and remove them.
Also, some states are cracking down on distracted driving, and adding much more than a cellphone and CB that is visible while driving can lead to more hassles than they are worth.
