My suggestion is that you watch an INTERNET TV show..
http://twit.tv/hn
You can grab most any episode, Look for one of the principles, Don who does the Newsline report.
He has an HF equipped JEEP and ICOM is a sponsor of the show... They give his contact info during the show.. E-mail him.. I am fairly sure they will respond.
I've had E-mail chats with a few of the folks on that show..
The show is live at 9pm Eastern time on most Wed evenings, you can watch live and also open a 2nd browser window and join in the IRC chat (Just replace HN with IRC and it should work) IF I'm there it's under my call sign.
But Don would be the Jeep owner.. He's needed it a few times already.
