We have a 2014 Eagle 298RLDS. Our unit came with a slide lock for the panty slide. We used it on our first trip last yr which was 2 hours away. Haven't used it since. We traveled from AZ to MN and back on all types of roads without any issues. On our PDI, nothing was mentioned about using the lock, even technician didn't know how to use it. Go figure.
