A small side story about my brother regarding an RV water pump... He bought an older half way decent motor home but, the water pump was buried inside an island peninsula on the floor under the cabinet. It was so close to the outside wall even twiggy couldn't get to it. I cut an opening in the side of the motor home and placed a 20x 20 matching compartment frame and door in perfect location. He came home and saw that, could not believe it... the water pump was right there handing you a piece of cake when you opened it. LOL, he was very happy to finally change the bad pump for a new one.
