Hi I purchased this 2015 parker 2530 couple months ago. I am working on removing the kitchen galley and installing a bench seat in place of the kitchen galley. i have disconnected the plumbing and electrical on the kitchen galley. I also removed the water tank and the countertop. Now my problem is how to remove the kitchen. cabinet i don’t see any screws that connects the corners. Looks liken it's a one piece wood. Any advise? Thank you.
