I have just purchased a new 2022 3121CK. I take delivery next week. I want to install an additional 600 watts solar (200 watt panels). I plan to use strut channel. While doing so I want every screw that penetrates the roof to enter a roof truss. And I want to limit penetrations making each count. Only, I don't know where the trusses are.

I've emailed keystone days ago. I got a question asking for the vin which I provided. Haven't heard from them since.

Does anyone have a roof plan or some idea how I might find the trusses. I've previously tried to find the trusses using a stud finder on my Arctic Fox. This did not work. Thus I don't expect it to work on the Montana.

I know that there are trusses bordering each side of the 14X14 vents. I would expect that other trusses would be on 16 inch center from those trusses, but I saw a photo of the trusses that showed me that this is not correct. It looks like they've done some unpredictable spacing adjacent to vents.

So, how do I find the trusses? Better yet, does anyone have a roof plan?

Thank you

There is no need to find the trusses. My 6 panels are only fastened to the roof decking, 2 screws at each corner. I first fastened the feet with that heavy duty 3M double sided tape but on my roof that doesn't do much but it was free. Just use stainless, puddle Dicor first of course and 3/4" long IIRC. I don't know of anybody fastening to studs, just not needed and many RV's don't have them or can't find them.
