Vortec knocks when cold
GM has a TSB for Cold Knock from the Vortec engines. Noise is due to excessive bearing clearance.- Snowman

Towing a camper
I hauled a small (8') slide in for a 3200km trip in January. It worked just fine. Didn't bog down on hills, and was quite stable. Didn't feel top heavy. Also I can take this hunting in September and tow the trailer with the quad and bar-be-que. -
heavy tapping at cold start
My '98 does the same thing. There is a TSB about it for the Vortec engines. Knock caused by excessive clearance on the 5th main bearing.- Snowman
