RV Specific GPS

I have a RM7725 (Good Sam brand) for the motorhome. I really like that I can set the height and length of the MH and toad and it will avoid routing on roads with sharp turns and/or low tunnels. You do have to set your road preferences; "avoid small roads," etc. I also like the campground search feature. It takes a little getting used when compared to the Garmin I use in my car, but now that I am familiar with it I like it better than the Garmin. It is easier to enter addresses and search for POI's. I haven't had any problems with it, it works well, has never locked up or frozen.
