Slide-out problems include motor/gear failures, worn or leaking seals, and water intrusion at the slide floor. Test every slide fully in and out, inspect the seals, and check the floor, repairs range from cheap seal work to costly mechanism replacement.
What it means
Slide rooms extend on electric or hydraulic mechanisms and seal against the body. Mechanism wear and seal failure cause both operational and water problems.

- Grinding or straining motor noise
What to inspect
- Run each slide fully in and out twice
- Inspect top and side seals for gaps and wear
- Check the slide floor and surrounding floor for softness
- Listen for grinding or laboring
