What makes you believe I don't have that spread sheet?

My engine is under the care of one best cummins service centers in Puget Sound. I'll trust them over a internet expert any day.

I was talking to the OP.

Our coach is 18 years old, the coolant filter has been changed once, the fluid never, it still tests good, still is a clear green. and will be changed when it shows bad.

Tom,

Yes, I assume you are using the three way test strips.

They test for:
Freeze point
SCA concentration
pH

It is often the pH (coolant becomes acidic and starts "eating" coolant system components) that triggers a coolant change.

That is what an anode is for.

not only be checked for freezing protection, but be tested for electrolysis.

Every five years ALL fluids should be changed; differential, coolant, power steering, transmission, air suspension desiccant filter,etc.

I agree, with the exception of changing the air dryer desiccant more often if your MH spends a lot of time in the rainy north west. Add the oil in the front wheels if you have it.
