Hi. I have a 2020 Flagstaff 21DS and want to put 2 200Watt solar panels on the roof. Plenty of room. My question is: Do I have to find the beams or can I just put the Z brackets into the plywood? I'm using Z brackets.

If I need to find the beams, how do I do that? I don't think a stud finder would work as the 21DS has an aluminum frame.
Thanks
