Wife overheated the 2005. . .

Snowbuck- try wrapping the heater hose connectors at firewall and manifold with TP. If it gets wet it wrinkles or disappears. Good for finding small leaks.

X-cellent idea. NJ garage just put in dye and finds nothing leaking. Will be driving back to MD and UV check it again. Seems I can buy a UV lite at Auto Zone or Advance Auto.
P.S. - is there any amount of losing coolant that is "normal"???

Yeah, during that motor rebuild project, I knew that I had a keeper in her. Why she decided to keep me, still remains a mystery to this day.

Probably because she was smart enough to know you were right, you weren't a dick about it, and it's clear y'all worked well together.

How long y'all been married, if I may ask?

no, you will want to check directly under the water pump pulley for leaks, it is hard to see right there but you can get under the truck or use a small mirror, you can buy one at the autoparts store they are only a couple bucks and they come on a telescoping rod and pivot to any direction. also check you steam pipe crossover that goes from head to head right under the throttle body also check the caps on the opposite end of the heads, and also check your rear passenger heater core connection under the passenger rear corner of the truck behind the rear wheel.
also look under the bottom of the radiator where it sits in the support bracket or look straight down both left & right sides if you see any wetness there then it's probably the radiator everything should be bone dry except the spot where condensation hose comes out left front almost right under the firewall which also happens to be where the heater hose "T's" connect so inspect carefully, the hoses that come out off of the water pump can get a pinhole leak or the reservoir tank can leak also. a small leak can be hard to find but just keep looking. if you still can't find anything then do a block test.

if you get the uv light and don't find anything externally, pull a valve cover and shine it in there. hopefully your oil doesn't light up.

OK...now where's MY coolant going??? Have to add about 3/8" to the reservoir every few weeks. Dealer finds nothing. Garage #1 replaces radiator cap and hose clamps. Garage #2 does pressure test = OK. Garage #3 does dye test and another pressure test = no leaks. Oil always looks perfectly good. No white smoke front or back. So after 4 garages...I still keep a gallon of antifreeze in the back seat !!!!!

Just curioys--do you have 862 heads?

45 years and counting.

Update: Radiator side tank has a three inch long crack on the left side below the upper radiator hose connection. There was some coolant left in the radiator. Not sure about the engine. So I'm going to do the obvious thing and replace the radiator since I got it out in about a half hour. Helps that I previously did a radiator on another GMT 800 with a crack in the same location. The drain plug was not missing after all. But the truth still is that it did get overheated. So fingers crossed.

They all crack in that same spot.
