I recently purchased the Garmin 770 RV GPS. I've only used it once so far and it does warn about low bridges as well as weight restrictions. The only thing I've noticed so far is that it does not warn of tunnel restrictions. It has a lot of great features for finding gas, food and campgrounds as well.
Sorry, there was a problem. Please try again later.The Garmin 770 LMT-S series includes detailed maps for North America that also include RV-related restrictions – like bridge heights, sharp curves, weight limits and more – and related information for most major roads and highways. It also includes a directory of RV parks and services.
