This doesn't work in a ideal manner. You need to select all relevant categories. If you are looking for 13 feet and under, you need to select all height categories 13 and under all thee way down to 7ft.
I use information from the state but it has turned out that some of their information could be way out of date. Always use caution with every overpass you encounter on a route. Better to stop and look or turn around than have a disaster.
AllStays Pro keeps getting better. We have always received a lot of requests for full screen maps for computers, GPS downloads, Google Earth offline and many other things that couldn't be done either by app or a advertising support website. So this new service helps with that. Along with full screen maps, we add more filters by price, stars/reviews, elevation, weather layer, traffic layer, biking route layer, transit map layer and more. AllStays Pro is here.
