You would have to make a hole in the galvanized box to get at the dump valves & see what's going on.
It was your thread that I was up til 1am reading last night. It was GREAT!!!
The section on the sovereign
that had rusted out was just below the valves and it was at least 18-24 inches square. I was in my office clothes in 110F heat so chose not to crawl underneath for a closer look...but now feel shamed having read your thread.
When the CO told me it had been in Florida, I began to get concerned about other parts the would corrode in that environment left exposed as much as they are. However it's possible the exposure allowed the rest of the pan to drain and dry out. It's currently parked near an open field, so I'm positive there is an entire alternate universe under there.
Thanks again! Your thread brought all kinds of images of fearless and industrious women riveting airplanes and tanks during WWII, so I got more than just good AS info from it!
