Here is the model I use, I have 2 handsets and three connection boxes.

This enables us to have one in the wife's truck, one in mine, and one in the tow rig. The guts to the radio are hidden inside the ebrake console, nothing to see.
Not that yours is bad, but I think mine is a bit neater in the end. It is invisible when the mic is put away in the glovebox. I also like being able to move it from truck to truck as needed. With the antenna on the rack, I usually have one of the longest ranges in the group, even with the small power of the radio. I am 100% happy with it, I even ordered two external speakers a few days ago to add to the setup for the ZUs so we can hear on the trail a bit better.
