Drycreek, I have a Magellan RoadMate RV9165T-LM that I bought from Camping World several years ago. My first question I would ask you is do you plan to use an Apple or PC computer to do the updates to your GPS? My experience has been that Magellan does no longer support Apple, but they send you to a 3rd party website now to get the updates. Other than that, the Magellan RoadMate is a good GPS. I recommend that if you do decide on the Magellan, download the full manual from their web site and spend some time getting very familiar with how it works and how to set it up properly.
