I've found several exterior attachment screws that were over-tightened at the factory, resulting in stripping out the material they were screwed into. Affected were a clearance light, my roof ladder, and a storage compartment "hold open" latch. I'll bet there are more. Either Jayco does not use torque controlled tools, or they are not adjusted properly.
There's lots of advice and information in forums... sometimes it is correct. For example, all of my posts are made by a political appointee who got the job as a reward for contributions to my diesel bill.
