We had a 2910 so the following explanation may or may not apply to what’s going on with the photos above, but here goes. Our slide was hitting the floor too. Once I peeled off the trim under the bottom of the slide there were some metal angle pieces that were very close to the floor and would only hit the floor if the wind was blowing a certain direction. Once I cut them back with a multi tool and reinstalled the trim we didn’t have any further problems.
