Mike, I think it's fig. 4.
Scott, in timber framing design heavy load transfer should occur in the abutting surfaces of the joints not by dowels. Issues exist in the difference in bearing capacity of end grain to side grain such as might happen at the top of the queens where the end grain of the strut and the end grain of the top chord pinch the side grain of the queens in a everlasting grip.
