Very good points.
My old diesel Ram (with an EGT gauge) would cool right down even after just 1 or 2 down shifts while coasting, to under 300F. Only after a heavy tow did I actually have to idle a bit to get EGTs down.
I imagine starters are better now, but wouldn't a starter cranking on a diesel be working quite a bit harder with the higher compression it's fighting at first? I know they're more heavy duty, but just a thought. In your situation I would probably be killing it.
