Brad,.....that TMS that you're refering to is nothing more than 6 BPS 370 boxes in a flimsy plastic container. Just about everybody I know who has a 9 series boat, ends up taking the plastic container out, and using the 370 boxes without that tray,...infact, I can add 3-4 more boxes without that tray in there!!...In my opinion, if Nitro wants to make a decent TMS, they ought to mold slots into the sides of the compt's like Triton does,....it's much more efficient and user friendly! I took my tray out and just store the individual 370 boxes on their sides with labels on each box...i can store A LOT more stuff that way. Hate to bum you out, but that tray is more of a pain than it's worth!
