I have been looking at the Garmin GPS units too as I have them it in my car. I noted that Garmin did not list “Propane Restrictions” on its list of “it does”. I emailed Garmin and ask if it did do the propane restrictions and got a negative reply, That is one thin that it does not do. Further research and I found that the Rand McNally GPS does all the Garmin does and much more. It is offered by Good Sam (http://blog.goodsamclub.com/2013/05/good-sam-gps-makes-rv-routing-simple/) or at Rand McNally’s web site. I believe that there are local dealers too. It is my next RV purchase (sorry Garmin).
