I've played the same radio for about 10 years... in truck, van, didn't matter, same setup.. and it is in my personal vehicle now.
It's an old Cobra 29 LTD classic with talkback and Superstar Echo Power mic. I know there are a lot more powerful radios out there, but this one sounds good as long as the echo level is low, keying around 4 swinging 15 or so, and I run it through a Francis 5 foot fiberglass whip.
