I think this would be coming from where it was built. I would be very surprised if the factory did not have a sheet like this.
For me, the maintenance against leaks and water damage is very important, and it’s what kills units. The manual is pretty general when talking about checking seams for leaks. Sure, I know to look at all the seams a few times a year and apply the Dico sealant on it. However, that hasn’t always worked out for me, and a seam that I didn’t expect to leak did. I guess why I’m concerned so much about leak on my new 5th wheel is that I have had two models before this that had water damage from a seam that was hardly noticeable, and then the “de-lam” starts, and we trade it in for one without problems. I have a new unit again and love it. I want keep it unit I get my 30k investment back (somewhat), and plan on taking every measure to the fullest extent, including have a “ bubble seal check done every spring.
A check sheet like this would provide me with more knowledge about protecting my investment before I curse out the manufacturer on how cheap their model was when I could have been more proactive on maintenance and up-keep.
