Google Maps is the best general-purpose map in the world. It is also not built for a 13-foot-tall, 30-foot-long rig — it does not know your height, your weight, or that the shortcut ahead has an 11′ 6″ railroad bridge. This guide explains exactly where Google Maps falls short for RVers and what rig-safe routing does differently.
Consumer Google Maps routes for a generic car. It has no field for your height, your length, your weight, or how your rig handles a grade — so it optimizes for time and distance, not clearance. That is exactly how RVers end up nose-to-sign with an 11-foot railroad bridge on a “shortcut,” or crawling down a 9% grade the map never flagged.
None of this is a knock on Google Maps for everyday driving, where it is superb. It simply was not built to keep a 13-foot, 15-ton vehicle out of trouble.
Rig-safe routing starts from your vehicle. You enter your dimensions once, and the router treats a too-low bridge or a weight-limited road as impassable — it plans around them instead of sending you toward a sign you have to catch yourself. It also weighs elevation and grade, so you can prefer a flatter road when one exists.
Camp Roostly does this on your phone and on the dashboard through Apple CarPlay and Android Auto, online or fully offline for the stretches where the signal drops. It also tells you something Google Maps never will: whether the campground at the end of the drive has enough cell or Starlink coverage to get a workday done.
Keep it for what it is best at — traffic, local businesses, walking directions, and quick lookups. For the RV drive itself, route with an app that knows your rig.
Camp Roostly plans around low bridges and steep grades, then navigates turn-by-turn on CarPlay and Android Auto — with a connectivity verdict on every campsite. Free to start.
