You can maintain or not maintain your truck however you like, I don't particularly care. However, no amount of "feather footing" or slow driving should cause your coolant temps to drop the way you described. It is indicitive of a thermostat that is not operating properly.

Your previous post referenced frigid weather. Now, it's +25F - +35F. So, you don't think there's a big difference between -20F and +25- +35F????? That's only 45 to 55 degrees apart.
1. My cooling system is in better condition than yours. Perhaps you need to take a closer look at your cooling system.
Made the same trip today in +59F weather. Coolant reached 198F flooring it from 50 -70 MPH on the highway with oil at 201F. Oil temperature was 194F and water was at 191F in my driveway because I floored it up a 7% grade 1/2 mile from home.
In case you can't read between the lines, I think online diagnosis of any problem is 50% guessing. When it involves driving style, weather, route, etc., it becomes 96% guesswork. If you think a 55F difference in outside temperature is not material, it's 99.98% guessing. I think.

Do yourself and the truck a favor and change your thermostat, and something else is wrong with your truck or the gauges that are giving you these readings. Going from 50 to 70 is a matter of a few seconds, at least it is in my truck, no way in hell would I get these high readings you posted.
