For the vent leaks I'd apply some Aluminum HVAC tape to the outside over the slots. It can removed easily if he want to use the grill for regular grilling.
Nice job on the build.
I checked it out when I built my mini. If I remember correctly, the upper mounting bolts would interfere with the base of the Tamale Pot if I used the stock lower holes. Maybe bending up some new legs to fit would work.
Not sure if it's the picture or not, but this kinda looks like a 1st gen. 14.5". If it's not, it's still a steal at $35.

Sorry if it was posted earlier.
I totally agree that the price is stupid.
But like I stated. I wish the U.S. had more color selection.
Compared to other country's, our choices are lame.
