After I made the LazyDays rally, I changed the oil and just got around to sending the sample to BlackStone. They called today and there is an 'issue'.
The sample shows 1.22% antifreeze and antifreeze can cause extra wear in the engine as evidenced by higher than expected metals content. About 4 times normal for a 3000 mile change but I really don't know how long it had been or what happened with/by/to the PO. Also the lead was almost 20 times normal which COULD be caused by leaded gas. I just don't know. I've put some real gas in since I changed the oil but who knows what happened before.
In retrospect, it was pretty stupid not to have immediately changed the oil when I got the coach...but it sure looked good.
I've got about 1000 miles on the new oil and as soon as they send me a new test container, I'll pull a sample and retest. I have absolutely no idea if the PO accidentally poured some coolant in the oil or not. It wouldn't surprise me given some of the other things but I suspect the worst, a blown head gasket or small crack in a head. It runs too good to be a big problem and I'm not seeing any coolant loss now that I've got all my external leaks fixed.
I'll probably have a better diagnosis in a few weeks. I suspect I'll be going through an engine this summer.... 
If I do have to go through the engine, I'll probably drop the whole front subframe. I've got a 1 ton front end on order and want to do the drive chain thing and install my 'new' 321 and it just seems easier to drop the whole thing and work on it on a table.
Trying to be optimistic but 1.22% coolant just ain't good and there really isn't any other way for it to get in the oil other than some dumbass pouring coolant into the oil filler. I guess that is a possibility but I'm not counting on it.
