I run a Ranger in my Cascadia with factory antenna (one for CB, other for am/fm) with no SWR issues. My radio adjusts automatically. I don't know the numbers, but I know the needle doesn't move much. I have never heard of an xpo driver having an issue with grounding or antenna problems. The coax does get pinched and have had that replaced on a couple, but that's it. Our tractors are set up to "plug and go". To the original poster, radios are good for info and to talk if you run with someone regular, but they can be temperamental and tough to troubleshoot. As a couple have said, it depends on how much you want to spend and if you need the full set up, radio, mic, coax and an antenna. A cheap Cobra will be $100 for the radio, but you could spend $500 or more if you want something with more range, bells and whistles. Other equipment needed can also vary in price a lot. I would ask someone at your barn who runs one what they have, if they like it, and go from there.
