2019 Oshkosh. The big bedroom slide which houses the slide in slide bottom flooring where rollers are is rotting. Heartland had stainless steel sheets (where rollers were gouging into the plastic membrane covered board) put in after one year when we first noticed the rollers were damaging the board. As time went by we started noticing the board become wet and rotting and couldn't figure out how/why it was getting wet. Turns out the facia along the outer bottom slide out is separating and causing water to flow in and soaking the board. We've had two estimates done and the cost to fix is huge. Heartland says they will cover under the 3 year structural providing it can be determined that the damage is due to a manufacturing defect. Seems to us that the outer facia (framing) should have more screws to hold it into place as ours seems to be sagging thus separating the facia from the outer wall. We've used silicon as a temporary fix but isn't helping. Has anyone else had this problem? If so, did Heartland help???
