Bill,
Search my posts in B+ motorhomes thread. You will find my answer to the leaking slide plus lots of other problems and fixes.
I currently am scheduled to have the slide worked on once again. The "base" the slide slides on is loose, and as a result the slide loudly and harshly and slowly grates/grinds its way in and out. This loose base allows the slide to "sink" just enough during driving (or with a person's weight on the couch) to remove the tension on the slide's articulating side arms. This allows these arms to rattle (which was one of my complaints long ago) and the "sunken" slide to scape along on its base when moved in and out.
The convection microwave trim piece/mount also broke on our last trip. I removed the oven and found the factory added subfloor in the cabinet was installed so as to provide no support for the oven's front legs. The oven's front trim piece has therefore been the sole support for the front of the oven, and it ultimately broke. Correctly repositioning the subfloor took about 5 minutes.
Quality of workmanship is miserable on these units. It is miserable on most RVs regardless of price paid. I hope this will be my last complaining post, but I am neither young nor nieve. Nevertheless, I am keeping this rig because it suits our needs and gets better and better with each fix.
