There are two things you can do that I think would fit your needs,
The first is to get a magetic CB antenna that can sit inside your cab while you are not using it, then when you hit the dunes, just extende it to go out the back window.
The second thing you could do is to get an adapter that will allow you to hook up your CB to your radio antenna. These work well, the range is not as far, but if you are on the dunes it should fit your needs.
