Rear light mount deatils

well, more off, and we are down to the bare floor, here is some detail of the trailer plug and light mounts with the mud guards removed , again we see how the hull is built by sandwiching the plates to form a rigid structure . In the middle pic, ive turned the end plate up so you can see the stiffener that is welded inside
the side plate is bolted to the side hull armour, then to the rear skin, and the bolts pass though to the rear bumper U channel
