Hi,
We use Baofeng ham radios off road as well as Kenwood, Yaesu, etc.
I like the handheld Baofengs, they are dirt cheap and if you hurt one, oh well. They work very well...

Pros- Cheap, functional, easy to program (See CHIRP programming)
Cons- Need a license for ham radio

But you can load FRS/GMRS frequencies and push them out at a higher wattage. The ham guys will say ILLEGAL but GMRS is pretty much the off road standard now.

Baofeng has a new 8 watt radio (output) that charges off a USB cable in your car and is very handy.
