Thanks for this information Dave.
I was able to find the heater core per your instructions. The heater core didn't really have any dirt on it at all.
I left the cover off for my 20 minute drive into work to see how toastie it would get in the truck with blower near max.
It is about 57 degrees out and the truck still didn't get that warm inside. But anyway, thanks for your help.
I'll probably end up replacing the heater core if can't find any reason not too.

Mike, how bout this reason not to.......... you said the "hoses" going into AND out of, the heater core seemed to be HOT.
This means the water is flowing "through" the heater core!!!!
Just fer sheeets and giggles......while you still have the cover off......run the truck down the road till the temp gauge moves up, and touch the heater core and see if it's hot. If it is... then it ain't a flow problem.
Sounds more like your problem is in the air flow across the core.
You need to be sure the interchange is working, letting the air actually flow across the heater core. Easy enough with that cover off.
the air prob'ly ain't flowing though......or the truck would be heating up........IF THE HOSES IN AND OUT ARE HOT......and the core itself is hot to the touch.
good luck,
