Ron, we have 2-ways as backup to cell phones, and for the first time in quite a few years, we used them more than the phones. Of course, during our heaviest storm, there was some electrical\magnetic interference that limited their use, for what I pay for air time, it is cheap backup.
My dad used CB's before 2-ways became affordable, but that was also in the day that AM radio was the only thing on the air too.
If you do go with a system, try to find one with a repeater setup, as I think I can get close to 100 mile range if the trucks happened to be on the far end of the spectrum.
I don't own the frequencies, just rent them. Also go with a trunked system, so you don't have to wait for another user to finish their hour long conversation.
