I'd do pro mod if you wanna absolutely be sure it'll take the abuse. A dunable is more forgiving but you're a bigger dude and it will definitely be mean on forks. If you're ok with opening cases a lot, go for it. At a minimum, I think Currie is doing the windows on stock cases now, or empire? That would be the way to go, but a really good pro mod can almost be shifted like a dunable. At least my unicorn WCR can if everything is adjusted right.
