I also bought the most recent copy of Delorme. So far, it has been proved to be difficult to work with, there are spots on the maps that are totally inaccurate, with roads that mislocated completely. The particulas spot I am looking at is not new, and is completely accurate on all the online maps, as well as the last copy of S&T. And the routes it picks from point a to point b are completely ridiculous, and only suitable for a 4-wheel atv in the dry season. As for any other option, the rand-mcnally product is what all my truckdriver friends, but you are talking about $400 or more.
