If it makes you feel any better, Keystone isn't the only one. Last year when we were in search for replacement for our Sunnybrook, Jayco was high on our list. The Jayco has a much smaller plate and only three screws.At least one in five right on the lot had broken door brackets.
The dowel trick may work but wood screws into end grain isn't very strong. Screw needs to go across the grain to hold well.
