RV specific GPS

You can buy a GPS that is made for RVing.

The advantage in most cases is that you can program, height, weight, length of your RV.

Most will also let you program that you carry propane onboard for those routes that may limit it. IE: tunnels, bridges, etc.

They do cost more, but are also usually higher end so their calculations-recalc is much quicker.

Mine is supposed to offer alternate routes during heavy traffic times.

My Garmin also warns me of steep grades coming up (ascents or descents).

In New England, NY and NJ we have some roads (parkways) that only cars are allowed on. No trucks or trailers and these units should help you avoid those roads.

I’ve been using a Garmin Dezl 560 for almost two years now and love it.

The Garmin I have has  the ability to download current stop light and speed traffic cameras INFO and warn you when approaching one.

The Dezl 560 also has a plug if you install a wired backup camera, it will display on the GPS when backing up.

Here is a listing of a few RV/Trucking GPS’s.

Most have similar features.

Good info. Thanks.

Do you know if any of those features are available on smart phone GPSs?

I’m not aware of any smartphone apps that do handle rv’s in the manner these specific ones do.
It’s still pretty much of of niche market.
I do have my copilot use a smartphone app (Inrix)for traffic.
Inrix is a mapping app on the Iphone which uses HD traffic info.
HD traffic is only available on a very few gps’s and none of the rv/trucker gps’s yet.
It updates every 30 sec as opposed to the traffic on normal gps’s that is every 5 to 10 min or more.
I don’t have a count on how many times the gps told me of a traffic problem and it wasn’t there or of a traffic problem that was there , but not reported by my gps.
I’ve found the Inrix app to be extremely acurate.
You can also inform the HD traffic system of a problem with your smartphone.
It’s one of the best out there.

I will have to play with my GPS to see if It has "truck" features.  I paid enough for it….it should have it.

Matt, on most of them, you need to input the info to first use it.
I have a couple of profiles setup in mine. One for the truck and trailer and one just for the truck.
It will route me differently based on the profile.
If it didn’t ask you that, I would doubt you have one.
Besides, you have to go out of your way to buy one.
I’ve yet to see one in a regular store. The only place I can go to put my hands on a couple of them is the local TA truck stop.

Great post! I’ve been meaning to look into this for a while now. 

Do you know if any of them have elevation information?  I’m towing much closer to the max than I’d like, and don’t know much about shifting with an automatic transmission (ok, shifting in general) and always stress out and white-knuckle the whole trip when large hills or mountains are involved.

Here’s a section from the Garmin Dezl 560

Drive Safe

dēzl 560LMT keeps you informed of upcoming road conditions, such as sharp curves and high winds, and restrictions, including no trailer or hazardous materials. A grade data field that appears on the map enables drivers to anticipate descents and ascents and shift accordingly. Trucking speed limits appear if they are lower than the posted automotive speed limit, and you have the ability to correct the speed limit on your dēzl 560LMT so you have the most accurate data at all times.

I think all GPS’s will give you your approximate altitude.

Unfortunately not typically easily available in auto navigation versions.

Storm Trooper – have you ever heard of an app for android phones that doesn’t use the phone network? I want a GPS for our trip in a few weeks, but my phone will be roaming… $$$!

There are two – OsmAnd-Open source maps Android and Navfree
These have the best reviews and so far, OsmAnd appears to be the better one.
Once I get in the states I’ll let you know.
