Ford has always had dumb oil drains.back in the 60's and 70's the trucks would flow across and into the frames crossmember . those trucks would leak oil for weeks after a change.
My Chevy silvarodo 4.3 Wt made a mess too iwith the 4wd axle and xfer case up there
I made a water-world slide out of al flashing.
I did like the gasketed re-usable drain plug and cast pan.
I'm sure the op will figure it out do the next try.
Big capacity, should be changing too often,
1 or 2x per year at the most.
