Ripped up and Black Streaks on Carpet!
What needs to be done is this.
Forget those Slicker Thingy's, they eventually will wear out.
Had the same problem on my 2016 38RL. This is NOT AN ISSUE THE DEALER CAN FIX!
The best fix for this is take the unit to LIPPERT SERVICE in Elkhart!
Took mine up there a few years ago, only to find out the Dining Room Slide was twisted and as LIPPERT Put it: This Slide was never installed correctly!
There are leveling bolts on the Slide In Mechanism that DID NOT even touch leveling spots.
Took them about 2 hours and cost $275. They see this allot at Lippert!
Forget about taking the Unit to REDWOOD, they are NO HELP AT ALL and if the unit is out of warranty, you can certainly forget getting any satisfaction from REDWOOD!
Lippert makes the Slide Mechanisms and they are the ones to take it too.
