A friend mounted a pair of those racks that others have mentioned on the ceiling of his TT. But he uses the TT primarily for his fishing trips... Plus he's vertically challenged (short) and doesn't hit his head on the reels.
As for me, I carry my fishing rods in a rod-tube, stowed either in the pass-through storage or in the pick-up bed, and the reels go in a tackle box.
