Get one with a detatchable head and mount the body under a seat. There a a lot of mini sized radios like the Retevis RT95. I use a box with two radios that sit on the floor either front or back and can easily be set up outside for events. There are ways to control the radio remotly and possibly through the vehicles Blue tooth and audio systems.I'm studying for my Ham Radio certificate. Anyone mounted a Ham radio in their truck yet?
I had GMRS in my Bronco but am wanting to move up in capability.
