The 8 Best RV GPS As Of March, 2021 (And 2 Other Models)
This page lists the newest RV GPS units that provide RV-specific information and generally include a built-in tripbook, such as the Good Sam Trailer Life directory in the case of Magellan models and, for Rand McNally's TripMaker RVND units, of course, the Rand McNally trip book, which existed in print way before GPS systems were invented. Expect features like customized RV routes (so you can avoid restricted areas and roads with low underpasses), RV parks, electric hook-ups, on-site laundry and water, and other useful establishments along the way, among other things.
The GPS models shown here were designed specifically for RV use and have displays of at least 4.3 inches.

A few other reviewers who praised the 760LMT, which, by the way has an average star rating of 4.5 stars, mention that its voice commands feature and ability to pin-point RV parks (A familiar, but still appreciable perk) are notable facets as well. The 760LMT's key features also obviously include specialized RV routing, which essentially lets users program the dimensions of their RV into the GPS, for more accurate navigation instructions, aiming to spare you the trouble of dealing with tight squeezes like low-clearance bridges.
On the flip side, some complaints about this unit include the fact that its incessant flashing of warnings (which the reviewer claims are already made clear by road signs anyway) is a distraction while driving. Some also found its connectivity rather sluggish, saying that they ended up relying on mobile apps and Google Maps to navigate, but that's in the context of so many other reviewers being fully satisfied. Another reviewer complained about its tendencies to freeze when driving into metropolitan areas, although he also states that a software update, which you should definitely take note of, while you're here, did the trick.
With that said, the 4.5-star 760LMT is Alphachooser's second best RV GPS 2021 and ranks relatively high when pitted against other GPS units of its kind.

Some of the criticisms made on this 4-star backup-camera-supporting RV GPS were more incidental than technical, with one buyer saying that it directed them away from a traffic incident up ahead, but led them into the center of a large city, which, as you know, is not the most convenient position for an RV or towable trailer to be in. Having said that, the same buyer mentioned that this particular model takes some getting used to, commending its snappy response to voice commands. Other buyers also praised this backup-camera RV GPS's elevation and grade features, which come particularly handy when driving over mountains. Additionally, some appreciated it for being easily programmable. A couple of other users even go so far as to say that it works as advertised, which is undoubtedly music to the ears of the folks over at Gamin.
Unsurprisingly, though, there were a few unhappy reviewers as well, one of them complaining that the 660LMT keeps on altering the routing without reason. Moreover, another buyer recalled a time when the 660LMT led them to steep inclines and curvy roads, instead of directing them to main highways -- a common problem among GPS, which sometimes depends on the settings you choose.
So, after scouring through a total of 783 reviews in this category and taking into account positive and negative reviews as well as everything in between, our shopping algorithm determined that the Garmin RV 660LMT GPS is worthy of a spot in the top 8 GPS systems with backup camera support.

Its Find Service function, which enables users to locate a nearby Walmart or Cracker Barrel (for quick rest stops) is also a plus for some buyers. Unfortunately, the 770 LMT-S was not safe from some brutal reviews, with one buyer stating that its mapping data led them to elevations of 8000 feet, nearly burning up the vehicle's transmission (We can't imagine what kind of pickle that must have been). Another buyer also complained that having this GPS unit take them 6 miles further than their desired campground location (which the GPS itself got right when he had programmed the address) was the last straw for him. That being said, many other users consider accuracy as the name of the game for the 770 LMT-S, with one buyer giving it a perfect 5-star rating for what he calls perfect routing. So, it looks like the classic GPS accuracy debate (GPS guidance is still an imperfect science and must sometimes be coupled with a discriminating driver, which explains the higher number of complaints in GPSes compared to other consumer products) continues for this Garmin unit as well.
With all that said, our review crawler algorithm, which surfed through a total of 8142 RV GPS reviews, makes us confidently say that the Garmin 770 LMT-S deserves no special award among RV GPS systems.
