I'm sure that model would work fine.
There are several of us that use the 75WXST (http://www.amazon.com/Cobra-75WXST-4...cobra+75+wx+st
) because of the size and setup. You can mount the box under the dash and only have the mic connected when you really need it... good for concealing if you're running topless or whatever. I'm not trying to change your mind or anything, just letting you know of some of the considerations I've had myself when choosing a radio.
I finally got mine installed and tuned for the Mineral Basin run last week and it was definitely handy and I recommend getting any CB so you can be more in the loop on the trail
