I do not recommend the Garmin 760 RV. In fact, I have been so disappointed with it that I called Garmin to complain about the flaws but got no joy. It occasionally directs to obscure routing like diverting off a throughway and then back on. Or directs into HOV lanes in big cities. The worst flaw is that the directions use local common road names instead of highway numbers. Garmin told me they changed to this because it aids 911 emergency vehicles. Not much help to me when I plan a trip using highway numbers.

I use the DEZL 770 Truckers GPS and love it. Has weight, height, width and length settings. It pays to learn it and study the settings and also to stay aware of what your last settings were. Particularly the route settings. It has several choices including fastest route, shortest route etc. I found mine routing me on state highway shortcuts one day and realized I had left it on shortest route from my last trip, staying on the interstate would have been better. Most of the time we use fastest route. It calls out sharp curves, school zones, rest areas and has many more features that I use.

After being lost a couple of times, confused a bunch of times and being directed to go from a 2 lane gravel road to a single lane gravel road in upstate New York, I decided to never fully trust my GPS again. I have a Rand McNally 7730 and it's led me to a low clearance, empty fields (You have arrived!) and the aforementioned gravel road necessitating a turn around in front of an amused group of Amish farmers. We now use the GPS, Google maps on the phone and a paper atlas to plan our routes. None of these formats is perfect but when you get 2 out of 3 to agree, you'll feel better and have a better chance of getting there. The GPS has options for shortest route and fastest route. I'd like a button for smartest route. Even when in RV mode and all my specs entered, the thing has an affinity for small county roads. It's been a challenge to keep from littering . . .

Wow! Haven't had most of those issues with my Rand-McNally 7720. The only issue that I have run into was when it told me to take an exit off a toll road in Florida and there was not an exit there. It would have been a 40 feet drop if I had made it through the retaining wall! :ohmy: Obviously, I didn't try. The exit turned out to be a half mile down the road. I have used this GPS since 2013 and upgrade the maps before each trip. The only other issue I have had with this GPS is that the internal battery no longer takes a charge.

I also research several different sources! We've had nearly every source, other than paper maps, try to steer us wrong had we not looked at all sources.
