You could remove the CDR valve and clean it in addition to doing the ol' ATF trick. 
While the truck sits unused.. can I/should I soak the cylinders?

That is a HORRIBLE idea!!!!!! What time?
Mine is clean, but also in a drawer in my tool box
If you want to thoroughly clean the pistons and combustion chambers, add a water injection system to the intake or air filter housing. It will clean up the combustion portion of an engine like nobody's business.
On a diesel I'd install a manual shutdown switch though so that I could turn the injection off a few minutes before turning the engine off so as to evaporate all of the water in the intake / cylinder system before shut down.
Back when I had my machine shop, I tore into a few high mileage engines that had aftermarket water injection systems. Some turbo - some NA. They were unbelievably clean inside.
Edelbrock used to sell an aftermarket water injection system that included a small pump, and some folks made their own using a windshield washer pump. Turbo gassers would use turbo boost to provide pressure as well. You don't want much water - just a very fine mist, so the injection nozzle in the air filter was very small. Usually you would go through 1 - 2 gallons of water per 300 miles or so.
Back then, the main objective for water injection was two-fold - increasing the air density and also cooling the incoming charge.
