We just bought the Garmin RV GPS. It has a profile that takes into account the RV height, width, and weight. We'll give it a try. Nice big screen and good mounting bracket.
I also have the Garmin RV760LMT and I am happy with it. With that said just remember that they are NOT infallible. BUT I did go in and set the options to avoid dirt roads; fastest route; as well as anything else that I thought would help. There is an option to avoid toll roads that I use when running solo but I generally set back to accept toll roads when towing. That option can route you in some squirrelly routes if you avoid toll roads when towing.
I also supplement the Garmin with my own points of interest (POI) like PPA parks, rest areas, etc. that I get from POIFactory.com. I do look over the route in MS Streets & Trips or Delorme Street Atlas. I don't get all flustered and delve into the route with paper maps, atlas, Google Maps, etc.
I have used a GPS from the days that Delorme had the GPS dongle that used a serial port. I did make the mistake when I first started towing a TT and followed the GPS blindly and it was a lesson learned. The first mistake was thinking that a automobile GPS would work well while towing...NOT. So when the Garmin 465T trucker GPS came out it was a good step up from the Magellan that was replaced.
Lots of people recommend to carry an atlas, paper maps, etc, etc. but if I am going to do all that I am not going to have a GPS. I have learned that if the route doesn't look viable, don't take it. I also pay attention to the road signage as well. As I said the GPS is not infallible and the maps can lag behind the real world. I ignore Gladys if it doesn't feel right. YMMV.
