So I decided to make a table that folds down that would support a grill or a cooler, etc. As I have a swing away tire carrier, i decided to mount it to that. so i bought some diamond plate and hinges, a 6 ft piece of angle iron for stability, and a hasp latch to secure it. Initially I had a 3'x2' but it blocked all vision out of the back, so I cut it down to the top length of my spare. No rattles and it works great. If I was to do it again, i would have just bought a thicker piece of plate so that i wouldnt need the supports. I also bought a piece of rebar to stick from the lock pin to keep the swing away carrier stable. Here are some pics. If you need advice on this, just let me know.
