I know that I cannot get a great assessment based off of a few pictures, but here goes.
I am concerned about these trees. The void where the two trees join, in the second picture, is between the to two stems on the right side of the bottom picture. This hole is about 4 feet deep and spongy on the inside. I cannot tell if it is just accumulated dirt and debris, bark, or rot. These trees all appear healthy and gets a lush canopy every summer. The reason I am concerned is that the one leader is hanging over my garage. I don't want to take the trees down if I don't have to.
I've read that these trees often grow with co-dominant stems. It seems to me that these would all be fairly weak since they are being compressed/girdled where they connect.
