I installed the cage yesterday. As Art and Joyce noted, there is no plywood to attach the cage in the area under the tub. So at the aft end, I attached a bracket to the cage and then to the box frame, then I attached the cage to the 2 x (?) at/near the outside edge of the exterior wall. At the forward end, I attached the cage to the steel gusset angle that extends out from the box frame behind the wheel well. In the middle of the cage, I attached the cage support "clip" to the box frame too. All in all, it seems very robust and I hope it is never needed. I paid a local fab shop to make the cage from 3/16" aluminum plate, following (somewhat) the design I found here from a "MisterP" post from 2010. The cage weighs approx. 12lbs., about the same as an extra heavy duty mud flap. I paid $98 for the cage, and about $5 for the attaching hardware. Here's my attempt at pictures;
