Anti freeze resevior drops down a bit now and then, had to add maybe 2 pints in the last month and a half. No external leaks to be found, Truck runs fine.
Try looking down around the right and left sides of the front of the engine, see if there is pink dexcool residue. Most often the water pump leaks at the block mating seals, this can be slow enough that it is able to crystallize and not be readily noticed as an external leak.
