... I still couldn't talk him into installing it hinge down, but I think the little door props will work fine.
Congrats on the door. Best upgrade I ever installed.
Unfortunately, I have to offer that he was probably right. Hinge down will not only put extra stress on the latch and hinge but also expose your new port to the vagaries of rain and dribbling water.
Good for him. Give your ever lovin' props...
then use them.
