Well, as promised, I am reporting back my experiences with this noise. It does happen anytime the A/C or the "combo vent" is on when the truck is started. Mine's the door closing.
So, I think everybody's suggestion to "live with it, it's normal" holds water. It does catch me off guard occasionally, though.
I have 2001 SD350 4WD Dually Extended cab. My dealer said the clunk was the A/C compressor unloading the oil in it on start-up. Not sure if that was it or not. Doesn't do it much anymore with 21000 miles on it. I do have the cold start-up clatter now. Steering wheel shimmy, doors touching at the top delaminated windshield etc. Not happy at all with my truck.
