RV Trip Wizard Low Bridge Issue

Last weekend, we encountered a low bridge that was not indicated in the RV Trip Wizard program. Let this serve as a reminder that although it's a tool, it's not perfect. Had I not been paying attention, I would have taken the top off my 5th Wheel. The bridge was on a secondary Lake Road just around the bend from the sign advising of the bridge so the bridge wasn't in sight prior to coming up on it. Had I missed the sign, I would have been lucky to stop before hitting it and even if I got stopped in time, I would have had to back up blindly about 500 feet to an area where I could have turned around. Fortunately, I got stopped and turned onto a road where there was no outlet but I was able to get myself turned around without any real issue. I sent the information to the people at RV Trip Wizard but just got an automated response that my message was received. Who knows if anyone will actually read it and add the low bridge to the program. Whether it's a trip planner, a GPS unit or other mapping program, never get too comfortable with any of them.
