I have a 3912 and the rollers just collapsed on mine too, destroying the linoleum flooring. CR warrantied the entire linoleum floor of the camper.
Note: The cause was the rollers coming away from the wooden framing. My dealer has installed a large piece of steel that runs the length of the slide (attached to the camper frame) that the rollers now mount to, avoiding any further issues.
Very dissappointed so far. I hope it all works out for you, your's is not the first Elevation to experience this problem.
2nd Note: My unit has been in the dealer 6 months of it's 10 month life for varying MAJOR/MINOR fixes. Crossroads has repaired/replaced everything so far under warranty.
6 months from now, I should have a pretty solid RV that I can trade...
