The new version of the Schwintek slides have no way to manually disconnect the drive motors and push the slide out in. When my main slide failed in November (just before a long trip) due to excessive wear of the gear tracks, I had to jack the slide-room up with a 2-ton floor jack, to un-bind the gear teeth. At that point, it was able to go back in. I was worried it would have to be towed back to the factory on a Landoll.
The ORV factory replaced the entire drive system on the main slide-room. Now, it's pulling away from the frame of the body. Also, I'm getting binding in one of the rear slideouts now. ORV will be picking it back up to fix those new Schwintek problems. My advice, avoid the Schwintek system. Luckily, I bought a brand who bends over backwards to support their product. If it were any other brand, I'd probably have had an accidental trailer fire by now.
