This is just an alert. I was driving on highway 41 in Florida. We came upon a set of "Rumble Strips" on the highway, which are designed to make a noise to alert drivers of pending problems on the highway. There was quite a bit of construction going on. I slowed a little and crossed the strip without a problem. I then made a mistake by slowing down. The next set of strips was hitting a deep pothole and a leaf spring broke on our 27' pull trailer. Beware these strips. I can't say the best thing to do is hit them in high speed but going in slow speed certainly caused damage. To make matters worse, had we been disabled, I had no cell phone coverage with my phone but my wife did. This is why we have separate providers. We terminated our trip and limped to our RV repair shop in Sebastian. Be careful out there.
