There are two distinct aspects to route and navigation tools. One is the advance planning, sitting at home in front of a computer. The other is navagation and route guidance on the road. For the full time RVers I guess these two are often the same.
But for me . . . the route planning long in advance, I still use the Good Sam Navigation Program on my computer, though that is now almost five years old. I realize there may come a time that it will be so out of date that I will no longer find it useful, but that time has not yet come. I did buy the later version put out by UnderTow, but without the information provided by Good Sam that was not nearly as useful. I have it on my computer, but always turn to the older version produced in cooperation with Good Sam.
It is really sad that Good Sam (Trailer Life) decided not to continue with support for this excellent planning tool. But they indicate no intention to do so.
As for on the road . . . I use paper maps and Garmin, but I have my own itenerary on shirt pocket sized paper which I have prepared in the comfort of my study as indicated above. All highways, intersections, turns, etc. plotted out in advance. It works for me.
Thanks for hearing me out.
