Wish I could do that with my Rand McNally. Apparently pre-planning on a computer, then uploading, is not possible for the Rand McNally. If someone knows otherwise, let us know.
I do what I can with pre-planning on the GPS itself, using way points etc. This would be way easier on my netbook computer.
I agree with Barndog about the advantages of having the RV size taken into consideration by the GPS device. This is the main reason I opted for an RV specific device. The Rand McNally has never taken me into a situation which the RV could not handle.
