That my friend is a genius idea. Instead of bolting the cladding on, why not make it out of steel, same overall shape but a little more angular and further out and have it be hinged on the bottom...It would double as storage for whatever you want, trail tools, jack, who knows...and for those with huge offset, it would seemingly bring them back in a bit. Like a widebody kit on a Nissan or something like that...*sigh* another project to think about.
Do you think the door could handle the weight? LMFAO, I had to say that, in case you didn't get it, that would be a reference to the rear tire mount project...................
