Thanks for the input Jim- best I can figure the lifter/follower noise was
due to the truck having set too long and the oil draining out of the top
end. Plus, the cold didn't help it either. The battery heater totally
slipped my mind, but I'll bet that's what it was! Thanks,

My GC 4.7 has never don't that yet and it has ben down to high 20s a couple
of
mornings.
My R/T will do this and I am told it is because late model Dodge trucks (and
cars maybe) have a battery temp sensor in the battery tray that causes the
voltage regulating device to raise the voltage slightly in colder weather
when more starting power may be needed and lower it in hot weather to reduce
overcharging and causing water evaporation from the battery. If you remove
the battery you will see a round flat plastic disk about the size of a half
dollar in the tray with wires coming out of the bottom of the device. That
is the battery temp sensor. I think I may have ruined a battery by putting
a piece of
wood in the bottom of the tray which prevented the sensor from measuring the
battery temp and causing a continuous overcharge in the summer. When I
replace the second battery i removed the wood and now the charge indicator
runs about a needles width lower.
