We had just purchased our new motorhome and embarked on a maiden voyage to Colorado in October. After travelling on ice and snow for two days we parked in front of a friends house along a curb. After checking for clearance we put the automatic step out. The next morning we left knowing the step would retract automatically when we closed the door. Upon starting out I heard a loud scrape and a bang so I stopped and looked only to find my mangled step hanging by one bolt. It appears the block of ice that was under my front tire last night melted and the step did not retract. It drug along the curb until it hit a joint in the concrete where it demolished the step. I learned to always listen for the step to retract before driving off.
