I'm leaving Seattle in a month or so for the AS rally in West Virginia & am contemplating buying an RV GPS. A Google search shows three possibilities:
1. The Rand McNally one you mention.
2. The Garmin that AWchief mentions.
3. One from Magellan.
There are also "trucker" versions at additional expense.
When I read reports on them on the Internet, all of them seem to have problems, & none of them seems seems to stand out as worth the several hundred $$$ each costs.
Is any one better than another? If so which? And is it worth the expense over a "regular" GPS unit?
Note: my Ram 2500 has an internal GPS, and I have an old Garmin in my car, which I could easily transfer to the Ram.
