I was thinking about getting a 5th rack for my #3 so I could do more ribs at one time. I then thought to try the racks out of my old MES30 smoker just on the chance they will fit. Good news is they do with a couple of caveats.
Width is OK, length of coarse is short. Two racks in one slot are about 4 in to long so there is some overlap. There is also a bend in the racks to keep them from pulling out to far when loaded in the MES that keeps them from fitting in the SI rack guides. It isn't very hard to flatten the bend so they slide in easy though. Sure glad I didn't throw the MES racks away when I disposed of the old shell recently.
