Anything attached to the roof's flimsy plywood panel that supports the TPO membrane would be suspect IMO. A few solar panels, yes, but not a rack capable of holding some weight.
You would have to attach it only to the underlying roof trusses but those may be hard to locate accurately. A sensitive stud finder might work.
Also I was just up on the roof of my 2021 Axis 24.1 today checking it for integrity. It already has one 100 watt solar panel and I found places for three more, but there is no place more than about 4' x 3' that isn't taken by something.
What are you planning to haul up there and how will you get it up there. Anything that extends the height above the existing roof A/C or Winegard (the two highest items I think) will be at risk of being swept off by overhead tree branches if you boondock.
FWIW I have already had the end cap on the passenger side awning and the one over the slide out hit by branches and destroyed the end caps. I must admit I do camp in some rustic heavily forested areas that don't have enough headroom for a MH.
