Dex-Cool
For all of you with a GM 8.1L engine, do you still use Dex-Cool, or have you switched to standard Long Life anti-freeze in the cooling system?

Are you guys using the GM recommended 5 year or 150,000 mile change interval?
The new to us 2007 Itasca Suncruiser 35L does not appear to ever had the coolant changed and there is some scuzz lining the radiater fill tube.
I need to change the coolant and with the gazillion complaints out there about Dex-Cool, I'm not sure what to do.
