2005 Sunseeker 27' Class C. How do you get the Suburban heater out? It's under the refrigerator cabinet setting on a piece of plywood that is setting on the top of the wheel well. It sets higher then the cabinet opening so cann't be taken straight out. Not enough room to tilt the back making the front lower to slip out the opening. Cannot go to the adjoining open cabinet area because of the water heater. I thought maybe I could take the cabinet front off but it appears I would be tearing out staples. Has anyone tackled this project. I just need to get to the sail switch.
