Very good report, very interesting. In late Sept 2010, we'd flown up to see our new granddaughter. My son drove us up to the start & a few miles up the Dalton.
He has plans (bucket list) to drive up it, but so far hasn't. They live near Fairbanks. I'll email him your report.
Some Pics from the 2010 trip:

At the start of the Dalton Hwy. same trip.

The Dalton Hwy.

Near where Dalton begins...the pipeline.

A rest stop at a pull out by a nice stream on the way back to Fairbanks from the Dalton Hwy.
