We have use the Magellan (don't remember the model) RV GPS for 5 yrs with very few issues. Sometimes it took us on a less desirable route because it goes the shortest but never where we really shouldn't be. This fall in VA getting off the Interstate it kept taking us back on interstate then to the next exit and u-turn back to the first exit. On third go around I realized it was the road sign sending me the wrong direction (weird intersection) and then Maggy was trying to correct it. It actually may have saved me from a bad situation. It is important to enter your size and weight and turn that option on. On ours you can switch to auto mode for when you are just using the TV by itself.
We were in Jersey City one time going to a location I was familiar with and wondering why it was giving different and crazy out of the way directions and then realized it thought I had the trailer with me.
