The ramp is built and the doors finished. I made the doors from 7/8 plywood, then trimmed with the same pvc trim is used on the rest of the structure. I applied these with construction adhesive and screws from the back side of the doors, so these should stay strong. The ramp i raised off the ground with a 6x6 since I will eventually be adding dirt in this area to regrade this part of the yard. Now I just need to caulk up the corners and paint.
