Bests & Worsts Reviews from Amazon

I've always been a Garmin fan and was thrilled to discover that Garmin had developed an RV specific GPS. I purchased the Garmin RV 760LMT and tried it out on local streets while driving my car. All went well. About a week ago we embarked on our annual winter trek with our 41' motorhome and towed vehicle. So far... EPIC FAIL! First off, the unit doesn't have an option to enter our RV's propane capacities. So it will route us into restricted tunnels. Of the eight locations we've entered into the GPS, the RV 760 has correctly led us to two! We entered a truck stop that unit suggested. We followed the direction off the interstate and immediately got that sinking feeling that we would not find a truck stop in this residential neighborhood. Then the unit pinged and advised us that we would be 'navigating off-road' for 1.2 miles! In a 41' motorhome! When we got close to our 'truck stop' we found ourselves looking at a funeral home. Another recommended truck stop turned out to be a convenience stop with fuel pumps. This one was impossible to access with our rig. And yes, the unit is in RV mode with all the correct parameters correctly entered. It's disconcerting to be driving along the recommended route and get a message that says, 'Unknown if current route is suitable for your RV'. Oh my freaking Lord, I bought this thing to keep me on routes suitable for my RV! Today the camel's back shattered. I entered tomorrow's destination into the unit. When I reviewed the route, I lost it! Had we followed the recommended route we would have driven down a long, narrow, winding road, down a steep hill to a ferry. This ferry has a 5 ton limit! I know this because we just happened to go out for a drive today and happened to be on that particular road. Our rig weighs 17 tons. And there would have been no place to turn around had we ended up down there. It's got some nifty features. But it fails do perform the most basic features that I require in an RV dedicated GPS. That is, keep me on roads that I can travel safely, and legally. Garmin has a lot of work to do before they can market a reliable GPS for big rigs. Buy something else or wait until Garmin works out the countless bugs in this unit.
