I dont see a GPS being a very good investment in a area such as Dallas. The GPS will not route you on truck friendly roads...GPS is mainly for cars. UNLESS they have came out with one that does truck routing
, If so, then maybe it would help. We have GPS in the truck but I rarly use it. I just call for directions and then look it up on Microsoft streets and trips to get a visual of where we are going.
