Well my first truck needed a shoulder into the door when flexed a little bit the one or two times I took it offroad. And it was bolted down correctly. The cabs are not rigid at all. I am considering a cage or at least a roll bar. That decision is a ways off yet. The wife and I are heading to Hayden and Post Falls soon. Any chance of picking up the crossmembers while down there? I can wait to if need be.
