Actually, I have been using a laptop with Streets & Trips for years now and it does a great job for me. I have plenty of friends who used CoPilot for a while but they all told me that it often tried to route them on restricted route roads and that it was far harder to learn and use than Streets & Trips and a bitch to do trip planning with. All of them are back to using Streets & Trips again. Anyway, I recently bought this thing,
www.truckstopsplus.com, and I can’t say enough good things about it. It has all the truck stops, superwalmarts, rest areas, weigh stations, and everything else and they are all accurate, not to mention that you can check your routes for restricted routes and low clearances on your laptop screen. It makes everything so much easier.
