A very wise GMCer PM'd me suggesting it might be a cracked intake manifold.
That fits perfectly with the symptoms.
While the coach had a slew of problems related to sitting for a long time; each time i fixed one (fuel filter, bad gas, etc) I would get a slight improvement but overall the problem kept getting worse no matter what else got better.
This seems to line up perfectly with a crack that is growing with each heat cycle.
I have not had a chance to back and test for this (ether?)

It's gonna take a lot of Adderall to get this thing right.
