Does someone make a GPS for motor homes that won't put you in a bad spot ( small street-tight area) or direct you to a fuel station that you can get into or a food stop that you can get into? You know what I mean
The best one for that is the 6" model found between your ears ;)
A GPS is limited by its programming and database; the developers work with what they have and cannot visit/survey everything. The database can contain things like approved truck/commercial routes, weight limit roads/bridges, and low clearances on commercial routes. Best practices for a new-to-you route would probably be to use Google street view and "drive" the route on your computer screen first, looking for potentially sticky situations.
Are there any apps that work with Google maps?
Michelle gives good advice, I use garmin RV 760 and like it a lot , but it's not infallible.
