Milton and I got the Rand McNally/Camping World 7725 about 2 months ago. So far, we've used it on 3 trips, it's working great. You plug in specific info for your rv and it gives you routes where you won't have any issues with propane, clearance, sharp curves, narrow roads, etc. I have no problems seeing it in the day or night. It has a tutorial on how to use it, it is user friendly, you get free map updates when they come out. It's just like a regular GPS system but for rv's. Last August we drove our Aruba up to Long Island. I had gotten a trip-tik from AAA for RV use. It was wrong on several points, enough to make me want to burn it, and we had to drive thru downtown Baltimore,MD because we couldn't drive thru the tunnel due to the propane tanks. That was a harrowing experience that we would never attempt with this 5th wheel. We have a Tom Tom but it regularly gets directions wrong, so we don't use it.
