Don: Truckers mostly use that coolant because it is cheap and they lose many gallons of coolant every year. BUT for Rv'rs I think the OAT is the way to go. Once you switch over there is no need for SCA and test strips. The price of OAT has dropped an it is good for about 5 years before you have to add the extender. Then you are good to go for 5 more years. Many of us on the IRV Monaco forum have switched and are quite happy. The test strips for the regular diesel coolant age after about 4 months and even then some that are supposed to be fresh do not work properly. A real pain.
