I have a 2004 Tahoe Q4 SF. I took the carpet out a few months ago, and I went with Durabak. I wanted to be able to spray the deck down when I finished fishing/skiing. I recently found a flaw in my plan. I do not have a way to drain the water once I spray the deck. Is there any way to install a drain. I know that the gas tank is under the center rear bench seat. I'm not sure if the area under the two rear side seats will drain anywhere. Has anyone tried this? Any suggestions?
