We recently purchased a Rand McNally RV GPS and had some significant issues on our first trip. However, we were able to work with the company to get them sorted out. Kudos to them for being so responsive. Here's what we ran into:
Problem 1. During set up, it asks for the length of the Tow Vehicle and RV. The answer was not as simple as we thought. We put in 48 feet because that was the length from the front of our Tow Vehicle to the rear of our fifth wheel. However, the GPS calculated this as a full length commercial vehicle, and kept us routed to accepted truck routes only.
Solution: When setting up the unit, Select travel trailer or fifth wheel, then put in the length of your trailer or fifth wheel only. In our case, it was 28 feet. This solved the problem.
Problem 2. While on our first trip with the unit, it kept trying to route us down dirt roads. It was very frustrating.
Solution: There is an option in the set up menu to avoid dirt roads. Once this was selected, it solved the problem. Note: The dirt/paved road preference is buried deep in the menu set up, so it wasn't intuitive during set up.
Now that those two problems are solved, we'll be trying it out again this weekend with a trip to Flagstaff AZ.
