So, it's that time again... Coolant change time. A year or so ago I went with the Peak green coolant with Fleetguard DCA/4 additive mixed in. Only reason I felt OK doing this was because the Peak green stuff said "Silicate Free" on the package. Long story short, after my multi-state trip over the last couple months came to an end, my radiator literally "pop'd" in the driveway whilst backing the trailer in for storage. 
So, pulled the radiator to swap in a spare brass unit, and the original radiator was slimed up pretty bad inside.
I have a feeling that the Peak "Silicate Free" crap was NOT silicate free, and the DCA/4 and the silicates got together and made a unholy mess of the innerworkings of my cooling system
I use only distilled water in the rig.
Also, the truck had a very hard time coming up to operating temp, and a run across the Arizona desert with minimal heat last month got my wife on the "you need to scrap this thing" rant again... So, I R&R'd the thermostat this past weekend. It was gunked up with the dreadful slime as well.
This weekend I am going to change the coolant. I would like to get the Fleetcharge stuff, but most of the usual suspect auto parts megachain stores around here don't carry it. Anyone have any luck finding it locally???
