Good morning Bill!
McClain RV in Rockwall TX has a picture of our 337RLS with a similar condition, although it was only the bottom corner at the front. We dealt with the slide having difficulty closing the last inch or two for a couple of months, with me (Steve) pushing the outside and Lynne operating the control. I communicated with Dean Brovont who sent me printouts of LCI diagnostic sheets and controller programming instructions. This helped for a bit, but soon the slide refused to close completely. We took the unit to McClain's for ou Atwood furnace inoperative, they changed out the furnace control board (twice, bad part), and diagnosed the slide issue as stripped gears. They ordered parts through LCI, it took at least two weeks for them to arrive, but unit was fixed in a day. I know you asked for just a picture, but I have wanted to post this for a couple of weeks to ask the community if anyone else has has Schwintek slide issues.
McClain's has the commitment to highest priority service form posted in their service writeup area and another copy in the customer waiting lounge. They delivered on their part of the promise, we were treated well in a quick time frame as soon as parts arrived.
