I responded to mddean on another post. We also thought that because the slide did not appear to extend all the way out and our cabinet doors did not open all the way, there was a problem. After sending pictures and questions to our very knowledgable PDI guy, he said the slides were installed correctly. The motor is mounted at the top of the slide and to allow clearance, the slides could not be extended out as far as they were designed. They made exterior adjustments and interior ones where they could. The cabinet doors not opening all the way is one casualty. The motor on the bedroom slide is under the bed and it does extend all the way as originally intended. It's just something we have to live with I guess. We have not had any problems with the slides themselves thus far. However, we have only had the camper a couple of weeks.
