And now, thanks to smartphones and RV GPS devices, we have all of that and more at the palm of our hands!

If you’re looking for the best RV GPS, listen up! We’re here with some of the best devices, apps, and tips for using these nifty tips.

What Makes an RV GPS Special

You may be wondering, “Why do I need a special GPS for my RV? Can’t I just use the one I have for my car?”

Well, you can, but you’re missing out on some important features that can help RV drivers out tremendously on the road. Some advantages aside from the obvious navigation abilities include:

Avoiding low bridges
Taking your rig’s weight into consideration
Avoiding narrow roads

Driving a large Class A RV isn’t the same as driving your car, so you shouldn’t use the same GPS. But of course, you don’t want just any ol’ unit— you want the best of the best that will get you safely from one destination to the next!

Tips for Using Your GPS in Your RV

Improper use of your GPS can cause distracted driving, leading to accidents. Always follow these helpful tips while using your GPS on the road.

Never fully rely on your GPS. It’s always good to have an idea of how to get to your destination— even if it’s as simple as knowing the general direction you’re supposed to be going. It is also helpful to download offline maps or carry a paper map or atlas in case of the unit’s failure.
Pre-enter your destination. Don’t wait until you’re on the road to start messing with the GPS. Always do this before you hit the road so you can remain hands-free.
Let your passenger help you. If you need to make changes to your route while you’re in motion, allow your passenger to do it. If you are alone, pull off the road somewhere safe, such as a parking lot, to make the adjustment.
Mount your GPS where it is easy to see but doesn’t block your view. Mounting it helps keep your eyes on the road.

But before you mount that GPS, you’ll want to make sure that it’s legal where you are and where you plan to go. That’s right— mounting your GPS is actually illegal in some states.
