Looks like I will be doing the same repair as you, but only because my piston bracket on the door ripped out - due to water damage - my wood looks like the ones in your picture.
What kind of wood did you use to replace the rotten stuff? I RV in the north during the summer, but use and store it in Florida over the winter, so I'd want to make sure to use wood that is good for water, but also dry rot and insects.
Hopefully you are still checking posts. And thank you for all the pictures in your post - they will be very handy for my work.
