I don't know if it would be possible to make this work.. ??
You know how places like 'Vonage' for example, sell residential phone service via 'voip' (voice over internet protocol), which is aka 'internet phone'.. meaning it is not a landline, but works off your internet connection.
I know someone who has been using it for over a year now, as their sole home phone line. The only issue is that in case of emergency, you should have a backup cellphone or something, since if your internet connection goes down or your electricity goes out, you have no phone service. This isn't an issue since these things rarely happen, and most people have cells anyway.
Anyway, the voip phoneline is a good half the price of a regular landline (at least it is here), and includes all features (call display, voicemail, call waiting, etc), as well as unlimited north american calling. Another cool thing about it is that you can control things from signing into your account on the computer, like you can block unwanted callers, block marketing calls, make certain ones go directly to voicemail without ever ringing, and you can listen to messages online, as well as save them and email them to someone else if you wanted to.
Apparently you can also take your 'phone' with you whenever you travel too, and the calls you make while away, are as if you were at home.. free.
Would this type of thing work with a laptop connected to the internet, while in a truck? It's a 'router', so if you have an electrical outlet, an internet connected laptop, and a phone.. is there any reason why this couldn't work? It would be a heckuva lot cheaper than paying the exorbitant cellphone fees if it could work.
