RV GPS and TPMS...yes or no

Here is a good review of our Garmin 7200. It rests on the dash on a block of wood tied down to keep it from moving around. It tells me how to go to wherever I want either the fastest way or the shortest way, by map and voice, and also tells me when I will arrive. It's FAR better than trying to read a map or a program on a laptop. It will tell me where there is fuel, when is the next Rest Area or campground.
It won't tell me the weather or show radar on the screen and occasionally `forgets' where I am probably due to a hole in the satellite coverage but soon recovers and keeps me on track.
The really bad news is that this model is no longer made but Garmin has many more to choose from.
If you just want to find a city a map will work just fine but if you want to find an address in that city there is no better way than a GPS.

We have had a very good experience with our Rand McNally LM 7720 GPS. It is designed for use by RV'ers and as such is packed with useful features. With a 7" touch screen it is easy to read, user friendly and very accurate. Got ours on Amazon for $269 and it comes with free updates for life.

I also have the Tire Trakker TPMS and a Scan Gauge all of which are constantly in use. It's hard to have too much good in formation at your fingertips.

:C

I have a Garmin RV760 LMT RV model GPS works well. Beware you can never trust any GPS 100% always verify its guidance with another source

I use a Garmin GPS and would recommend one. If you only want a GPS to keep you away from low bridges, forget it, there is much more use for one IMHO and it would be a silly waste of money if only for that purpose.

TST 507 here. I wouldn't travel without it.

Go with the TST 507, I love mine. Forget about the rv gps. Bank the money or buy more beer. Good luck

The only advantage I see with an RV or truck GPS, is that it is supposed to keep you from trying to drive under lower underpasses or routes that might cause you a problem.

Like most technology, it's only as good as the programming, and I believe that many of these are so so at best. Like you, I have seen reviews that were less than glowing. It may be that you will do almost as well with an inexpensive TomTom, if you also try and review you routes ahead of time.

The Tire Monitors are worth it, but expensive. Most folks have gone decades without them, if you maintain your tires and air pressures....but if I had the extra money laying around, I would probably invest in them too.

If the choice of your money was the Tires or the GPS, I'd go for the tires!
