Spoke with Norco about this known problem with these slide out motors leaking oil. Customer service gave me two options. First, the said they could send out custom drip trays for the 2 motors if I wanted to repair the problem myself. Secondly, they explained that Keystone would be the responsible party if I wanted to pursue a dealership fix. The referred me to Keystone's customer service dept.
I was able to contact Keystone directly. They were very receptive of my issues with the slide out roof bubbling. They said it would have to go through a dealership as they would need the pictures and dealer's input of the membrane. So I followed up with my selling dealer. They said that Keystone most likely would approve a fix for the slide out roofs, but the process would require at trip across the state to the them. I would then have to wait for an approval and return with the trailer sometime in late November/early December. The fix would include installing those drip trays and cutting out the loose material and patching most likely with Eternabond.
So, for the sake of my own sanity, my time, and my fuel costs, I decided to have Norco send me the drip trays as a courtesy and complete the repairs my self. The membrane wasn't perforated or torn, just bubbled directly under the motor. I had to remove both slide out topper fabrics to get access to the slide roofs. After thoroughly cleaning the roofs with dish detergent and denatured alcohol, I ran a strip of 4" Eternabond tape along the entire length of the OEM tape on the edge. I was able to crease over and cover both bubbles completely.
The TPO membrane is now well preserved over that area and I'm confident the dealer wouldn't have done a better job. For the price I saved in gas (180 miles x 4 trips) and my own time, it was well worth a few hours to work at my leisure.
I was also able to clean and condition the top slideout rubber seals with the toppers off and replace one of the topper fabrics that had a seam separation. So, a big "win-win".
