Roof brace?

[Project13thirty1]

Anyone know of any roof brace kits available for FR or RW highwall popups? Been searching around online and can't find anything. My roof on my hw27ks has a bit of a sag when viewed from the front or rear. I've seen a thread about someone using a roof brace kit to fix this issue but I can't seem to find that thread again.
I'm not opposed to building one. If anyone has any ideas of a design I would love to hear it.

Can you perhaps explain how it is "Sagging" ?

Looking from the front or the rear down the roof the center of the roof is lower than the edges where the side panels attach. I've noticed when it rains some water collects up there, not a whole lot or anything, but I don't think that's a good thing.

Depending on how pronounced it is I would not worry about it. The roof is suspended by horizontal braces going from left to right every so many feet with the roof on top. They started putting 1/8 or 1/4 ply above the frame beams then the plastic on top.

if its sagging and you push up on the middle you are pushing the cross braces up which may result in roof seal separation at the edges, water infiltration and water damage.
