The flexible vinyl section around the perimeter at the rear is for a penthouse, probably the mating piece to connect to conventional modular tentage. When that style of box is on an MLVW, there is an interface that not only has poles out from the floor of the box and a short arch pole back to the roofline, but a series of skirts that enclose around the issue ladder. Quite a clear but maddeningly only-fits-one-way piece.

The weak spot is a ball and socket knuckle at the end of the arch poles. MCE had those knuckles in storage because the troops used to break them (quite innocently) often enough.
