"JCat".....You say that you break out the Simple Green to clean your radiator. Are you talking about spraying the one side of the radiator and the one side of the Charge Air Cooler you can access? If so, I think you might be missing what's causing your base heating issues.
On your coach, there should be a large metal plate covering your engine, probably under the bed. When you lift this cover, you'll see the radiator and Charge Air Cooler (CAC) are sandwiched about 3" apart. Take a light and look down between the two. I'll bet you'll see what looks like hair growing in there. This cooling system configuration is VERY difficult to clean because there is no access.
My sister had the same chassis and her coach would run fine until we hit a grade in the heat. We spent quite a while using a garden sprayer and soaking the two inside faces of the radiator and CAC with Simple Green or Dawn. Then we used a homemade flusher we made with pvc, that looked like one of those toilet wands.
Using hot water directly from the house water heater, we rinsed the surfaces until the water finally ran clean. No more overheating. If you hit it once a year or so, it won't get nasty.
