As of now it is much stronger than the original roof structure, but it is not a full cage. Its primary purpose is to replace what I removed, and be able to lean against a tree without damaging the body. I do not expect it to fare any better in a roll than the stock sheet metal roof, but I imagine it would.
Going to be adding some more to it, but it isn't going to turn into a jungle gym. Taking the minimalist approach to it.
Working on placement of some spreader bars, and some rear diagonals right now.
