Best GPS system for class A

Hello Everyone

My name is Andrew and we have just purchased a large 37ft Class A motor home. We are now looking for a reliable GPS system. Can anyone recommend a good one. I guess that we are looking for one that does not take us under any low bridges etc

Thank you

Hi and welcome to the forum.

We've had good luck with our Tom Tom 910 for the past five years covering 50000 miles. But, if you're looking for something specifically for large vehicles, we'll have to wait and see what others might have in mind.

Best of luck.

I have a TomTom and a Garmin that I have quit using since I installed coPilot Live on my iPhone. It does permit you to enter your vehicle height, and will avoid routes where you might have clearance issues.

Unlike some smart phone navigation apps, it downloads a full set of maps initially, and does not need a phone connection to operate.

I also like the feature that lists fuel (can be set to diesel) prices, either in your immediate vicinity or along your planned route.

Do a search on the Garmin Dezl 560 and 760 LMT. The 760 LMT just came out and it has a big screen and better speaker so you can hear and see it when it is on and RV dash. Both models allow you to insert the dimensions and weight of your MH and will route you accordingly. One of the great features on these is the lane routing. If it knows you are going to take an exit or the road is going to divide it will show you what lane you need to be in way back so you don't have to make panic last minute lane changes and have them not let you in. They both come with life time map upgrades. I have been caught several times of my older GPS trying to get my 12.7' MH under a 10.5' overpass. No prior warming signs and I just happened to read it on the overpass and do a panic stop. Also have taken my 23 ton MH over some 18 ton limit bridges. Just held my breath to make me lighter and hoped I wouldn't be on the news.

We have the Rand McNally 7710 and we love the features, but it has the problem of viewing in bright light. I understand that the 7720 that just came out has taken care of most of that problem. That would be my choice right now. We tried the Magellan 965T and really liked the brightness and clarity of the screen, but it doesn't have nearly as many features as the RM. Good luck & God bless!

I just got a Rand McNally 7720 on Wednesday. Haven't even gotten it out to the MH yet. In fact I haven't even let it find the satellites yet. The screen is bright and I got the optional sunscreen for it.
Really can't say how it's going to work even.

Here's a discussion on the Garmin DEZL 760

If you take a notebook/laptop computer on your trips (a lot of us do), do a google search for gps aps for laptops.

Larger screen, 12v power plugs available, and there are many non-skid pads to keep it in place on the dash. More memory, many options can be entered as to you coach sizes as well as driving preferences.

Good luck !!

We have the Rand McNally 7710, others have expressed lighting issues. I guess we have the proper mounting area as this is no concern! Personally we would not be comfortable without this system.

I second that, I installed the Magellan software on my Mac and found it cannot be removed by any normal means. Intrusive and a pita. Think twice before buying one.

Agree! If you can install a goose neck mount or an other method then a laptop is ideal. The large screen really helps you anticipate turns etc. I find it superior to my smart phone or TomTom. If this is not an option the larger Garmin recommended on previous post's may be best then.

I have a Garmin 560, Copilot on an android phone, MS Streets and Trips with GPS on laptops, an older Tom Tom, and a Rand 7710, and have used the Google voice directions on the phone. I kind of collect GPS units like some guys collect guns, tools, golf clubs or other toys. I personally prefer the 7710 right now and have had none of the problems others have reported. The truth is, however, all the units except the Tom Tom seem to be ok. I do not, however, drive many places where low bridges or weak bridges are a big issue, nor use the GPS much for POIs.

IMO, if you can go somewhere displaying a lot of the GPS units together, you can play with them and get an idea of which has the features you want.

I had a Garmin auto GPS that did not take into account the low bridges and one way roads, etc. After I scalped a motorhome on the Bronx Expressway going under a low bridge, I switched to the Garmin Nuvi 465 which is a truckers GPS. I haven't had a problem since, thank God.
