This is not what “RV Safe” means in this context. It means the GPS won’t route you under an overpass you’re too high for, or over a bridge you’re too heavy for.
Bumpy roads and railroad tracks are not “unsafe” for an RV.
It is a matter of opinion of what the context mean for RV Safe GPS. In my view it is marketed to mean exactly what it says "RV Safe GPS" so it is contextually intended to mean safe GPS navigation for a RV period.
With respect to bumpy roads, I said rough roads in that I reported through the RV Safe GPS feedback system.
WHY? Because
I have yet to see ANY type of road alert from the RV Safe GPS ; so I purposely found a legitimate road with a real road hazard (rough road / bumps), so I could see what the reporting would do. I have now reported that rough section of a road 6 or 7 times, but nothing happens. Now I give you that a rough road may not be unsafe for you, the point is that the RV Safe GPS does view a Rough road as unsafe for their RV Safe GPS App. See my screen in Android Auto. You can see below, they allow one to report
and view a "Rough Road" as unsafe.
I can give a real life example of why a bumpy road can be unsafe for an RV or any vehicle from just two weeks ago while in Oklahoma. I believe the City was called Checotah? I had stopped West bound off I-40 to get gas, when getting back on the freeway the onboarding ramp was really really bumpy, but you could not visually see anything that would suggest a rough road. It felt like I had a blow out. I was nervous thinking I had hit a pothole or something, but my TPMS was not showing any issues. I could not risk getting up to speed on that freeway with all of that traffic not knowing what was wrong; so I pulled over on the narrow side. I got out and this is where the danger comes in, I could not see anything and going around the entire RV on both sides with traffic on the ground worried that maybe it is an inside dually. It was nothing, but bad bumps on the ramp. I slowly drove to the freeway and all was good. My point here is that it would be nice if that rough road was reported and the RV Safe GPS alerted me as it is stated to be designed to do. It did not alert me. Nor is it alerting me for the hazards that I have reported. For similar comparison to Waze; you could be the driver ahead of me by a mile or so and report the same hazard, by the time I get there I will be warned by Waze.
I have never had an incident with a train, but I have never known any GPS (RV or not) that don't warn you of a railroad track

. I do believe some GPS systems have filters to turn off if you don't want. I worry more about what may happen from getting boxed in on a train track versus actually finding a overpass that is lower that 12 feet. Never seen a low overpass in my entire life, but I don't doubt some exist. Would love to find one that is my area just to drive by to see what happens. I suspect if it was really Low there would be so many signs that if I missed it, I would missed it on Navigation too. You have to be really stupid or special needs to hit a damn low clearance bridge. But back to railroad track, the point of these posts to this thread is to answer the question for OP or someone considering the RV Safe GPS. It is materially relevant to know that it does not alert you to where the tracks are. School buses are required to Stop by law and many other commercial vehicle do the same and it is all in the name of Safety.
