New Montana casters making dents in floor

[jdarwin]

Does anyone else have this problem? New 2019 3931FB purchased in Feb. About 4 to 5 weeks ago I started noticing a small dent in the bedroom area. After several weeks it continued to get progressively worse. I finally figured out it's the casters on the bedroom slide causing the problem. Both casters are making dents/holes in the floor.

Has anyone else had this problem? What did you do to fix the problem. Since this is a new unit (still under warranty) will Keystone be a stand up Co. and correct this? Thanks
