Wondering if any of you other 4100 SCA owners know what might be behind this area below the cabinet in the aft stbd corner of the saloon? Overhead of the engine space is closed, so can't look up. Since the cabinet above goes aft at least a foot, guessing it's not against the aft cabin's shower bulkhead. Figured I'd ask first before drilling a small hole in the bottom of the cabinet and poking a fiber optic tube down there to take a peak.
