This is the first consideration you need to make because some of them have customizable specifications to have the proper configuration for the RV rig. It will serve as a guide for you while going through routes that come with bridge clearances and roads that are for handling weight and RV dimensions that have towed equipment.
2. Bluetooth connectivity
A good GPS should have Bluetooth connectivity because there are some areas where you cannot use an electronic while driving because it is either illegal or discouraged. This is why some GPS systems have Bluetooth connectivity and they come with speakerphones so you will be convenient while driving.
There are GPS system models that are Wi-Fi enabled allowing the unit to automatically update itself while it is connected to a Wi-Fi, even while you are driving. This will spare you from having to remove the GPS from the vehicle because you need to connect it to your computer.
4. Updated database
Ideally, the GPS you will buy should already have its own updated database of campgrounds in the country where you are. It should give you a warning if you are about to encounter a steep grade, tight turns and a lot more. The GPS needs to have the ability to give you the actual speed limit on most highways and the speed of the vehicle, it will warn you if you go over the pre-set value.
5. Lifetime map and traffic updates
The GPS you will buy has to give you an update of the traffic for a lifetime because it should give you an alternative route when there is heavy traffic ahead. You can buy this separately or some of them are offered with a monthly plan.
Even if all GPS units come with a pre-loaded map, it should also have a lifetime map update for free that lets you maintain the accuracy of these maps while the roads are changing. You should constantly check for map updates that are available to start your road trip. If you need a world map, this can be purchased separately as well.
6. Consider the size of your RV
The specialized GPS for RVs are made to take into consideration the RV’s size and why it is being used. They are able to understand the RV’s height and weight and stay away from bridges that are not high enough or is not able to support the weight of the RV. In addition to this, this specialized GPS allow RV owners to plan their route before leaving and know which stops are RV friendly, like the ideal campsites for them. This removes the necessity to stop without the right hookups or the need to empty an almost full black water tank.
