Most likely had a small contaminant in one injector .    Luck is on your side.

Hannah and I really appreciate all of the input from everyone.  We're not convinced that the problem has resolved itself but we don't know what else to try.  It's definitely scary hitting the road without knowing for sure.  I'd much rather be broke down at a nice campground than on the side of the road somewhere.  It would be nice to be able to say that I fixed the problem but I'd settle for just knowing what the problem was and or why it is no more. HA!

Adding a fuel pressure gauge is on the list of things to do.  A pyrometer and boost gauge would be nice additions as well.

Both our Airstreams had them and I was surprised our's did not. The word I got from the Factory & CAT was, unless the engine had been 'hot rodded', there was no need.

Many older trucks and some rv's came from the factory with boost gauges and pyrometers.
Driving up a hill, with foot to the floor, may not cause coach to downshift, but you would be surprised how high the exhaust temps can get. If I cannot accelerate or am slowing down, with full throttle, I always manually downshift.

My dad a lifetime trucker long before automatics told me "if climbing a hill lift the throttle and step back down if it doesn't accelerate go to a lower gear" I used that info on all my trucks and never melted a piston.

We made it to Williamsport without any issues.  The coach ran really well, the temps were good,  it had a lot of power, the coolant and oil levels look good and the smoke is almost completely gone.  There is still a bit of black smoke when the engine is under a heavy load but it doesn't last for very long. 

  The exhaust manifold gasket is not leaking anymore.  That mechanic ordered us a set of multi-layered steel gaskets and I spread a thin layer of high temp sealer around the mating surfaces of each exhaust port on the head.  The head is pretty corroded at the mating surfaces and was allowing the exhaust to get past the gasket.

Ther was a lot of great information shared in this thread  and Hannah and I have really learned a lot from this experience.

Wonder if a resonator would help,few and far between but a couple of posters years ago replaced a stock muffler and it was full of
black carbon.

Usually mufflers taken off diesel have quite a bit of carbon inside. One of the reasons they don't rust out but may rust from the outside in if not stainless.  Especially true with mechanical diesels where the operator overfuels on grades. Sometimes, you can see sparks out the exhaust downgrade where the engine is passing a lot of air through and it ignites some of the carbon in the muffler.

You can prickpunch around the worn gasket area , raises the effective surface a bit and gives the gasket a little more traction .
