Kingsport (by Gulfstream) TT owners beware!

That really sounds like what happened. I never expected to get any response from the Gulfstream customer service, but they actually responded! :E
HE wanted pictures, so I forwarded those above to him. The response I got back was

"the plant your unit was manufactured in was closed during the 2012 model year ….………so I was unable to send to the manufacturing facility for review and or comment"

So ... basically what I suspected..... nothing.
It's all repaired now, and I'm confident it won't leak, (using 4" wide Eternabond tape, and lap seal. It's just frustrating as hell that I didn't have to cut the membrane at all!!!

Having worked at a trailer factory years ago, here is my take, or best guess as to what happened there.

The shop monkey.... oops,,I mean the highly skilled trained technician went to cut out the hole for the vent in the next truss opening.

These holes for the vents are cut out using a router. The guy on the roof hollers ROUTER! to warn others he is about to cut out a hole, so they can be clear to avoid injury. No joke, this is how they do it. He then touches the edge of the router to the roof on an angle and flattens it down, forcing the bit through the roof sheeting. He then runs it around the 14 X 14 framing.

So in his haste, he went to cut the hole on the wrong side of the truss. He moved the router in an arc to find the framing, and found none. Oh 4 letter word he exclaims as he realized his mistake.

He moves the router over to the other side of the truss and cuts the hole out. There, done. Now to hide the hole....
He grabs a staple gun and bangs off a bunch to "fix the cutout attempt. Then he grabs some metal tape, covers up his oops and sends it down the line for roof membrane to be installed. It gets covered up, the foreman doesn't know about it and nobody is any the wiser until years later some poor guy steps on it and thinks he has water damage.....

I can almost guarantee you that's what happened. And things like this are very common.

OSB on the roof is pretty sad.

Your TT is 11-12 years old. I'd be surprised if the manufacturer helped you.

We've all seen poor workmanship in our trailers and motorhomes. I laugh at the stickers they put by the door reminding you the builders used certain quality standards. I just replied to another post about how the wiring on our brand new TT in 2012 was partially cut due to it being stretched over paneling under the sink.

I think you are doing the right thing....fix it yourself. And most likely don't count on any reimbursement from the manufacturer.

I do envy those that can rebuild an old TT or build a new one from scratch themselves....I could if I had the time....just too much else going on and it's easier to buy off a lot.
