Bracket function??

[dirtyfingernails]

I just won this M101 trailer on GSA. I picked it up this afternoon. It was obviously a genset trailer (ground strap data plate, holes in floor, fuel can holders, fire ext). Can anyone tell me what this bracket on the underside is for? Is this a spare carrier? Also, what's with the big sheet of metal on the right side? Thanks,
Steve

mounts for the fule tank, the sheet metal looks like a sheild for the tank.
