I too have problems with my Shwintek slide room in my Palomino Solaire. It's scheduled to go back to the dealership (AGAIN) next month. The kitchen slide buckles, pops, won't move in and out smoothly and will not stop running even when the slide is completely out- it sounds like the motors will rip the entire slide room out of the camper if I continue to hold down the switch. I also find metal shavings and the other day found a snap ring on the floor underneath the slide.
OEM or not, it really doesn't matter to me. All I know is, I am one of many that are having these ridiculous problems with this type of system in these types of vehicles. Perhaps the Shwintek is simply not a realistic system for campers that are made cheaply and towed around on cheap suspensions. Perhaps the Shwintek is poorly engineered as well- metal gears with aluminum tracks, really? I also dread the day when I have to manually move the room in and have to dig for some control panel to disable the motors. My old camper had a worm gear that I could manually crank in the room securely (not that I ever had to in seven seasons of camping.)
