[The View 5046]

We in the past used CB's. But we now use OnStar and it works for us.... You will have to raise the antenna up above the 5th wheel to get a good signal.. My Freightliner worked great, but since we went back to GM 1 ton we can use the OnStar..... I also don't have to worry because with the turn by turn I don't worry when we get separated. Good Luck with your research.. I used Cobra CB's in both Veh's and I had upper and lower channels installed and didn't have to worry about the garbage on 19. Happy Trails....
