The newer tray design from RCM is a single piece and doesnt use the spacer any more. It lowers the battery a bit, but I dont think its a half inch. The bottom of the battery is around .2 off the chasis now. thats about as low as you can get it as slong as you are still dealing with the side mud guard. The sinlge piece is a bit lighter too.

Sounds like the MBX6 might have a bit of a low body on the sides. I had to bump the body up a bit to fit my packs without hiting the body on my 808, but only 1/8" or so.
