Im almost 100% sure the access is for rigging up a tow hook. The issue is that they didn't pre fab anything to mount to. I can only think of one way to utilize this access and have a removable tow hook. I plan on drilling a hole into the bumper behind the access cover and welding a threaded tube inside. Then screw in a I-bolt and tighten with a jam nut.
