The motor case is 1/4" lower than the barrel, so the added piece added clearance for the case and provided a place to pass thru the clamp.
The barrel rests on the the piece added to the top of the main bracket.
By the way, an aluminum floor strut is located right under the motor. You can see it to the left of the cut-out for the water lines going to the other side of the trailer. Nice spot to place the bracket screws.
I used sheet metal screws for the bracket similar to those found on the floor under the couch
