I take a bunch of crap too from people. "You can shut it off you only have to let it idle if you are towing a lot of weight, and that trailer you are towing is only 8,000 pounds." I told the person they should probably stop talking to me becuase it was becoming obvious they know nothing.

Can someone with a stock truck and a pyrometer post up how long they have to wait after certain driving conditions.
Like straight up driving down the highway, city driving, towing in city and towing highway. And try to describe their driving habits, like going slow for a few minutes when going through the neighborhood, or hammering on it and how long you have to wait to get it down below 400 or even 350.

My truck is stock. I'm only guessing on my numbers cause my gauge is numbered 300-600-900-1200-1500 w/ hash marks between. I know it would seem all you have to do is count the hashes and thats how I'll call it for this post sake. But keep in mind it can be alittle off.
My truck {04 F250 cc Fx4 Larait 6.0L} On flat highway @ 55mph runs about 700 degs. At 55mph hitting small hills the temp will raise around around 10,000 degs. This kind of drivinging and driving in town under 55 stop and go takes 2 minutes to fall to 450 degs. {I get 450 degs cause the needle it right in the middle of 300 & 600 degs. It might not be the right way but with this kind of driving I shut down when the needle drops below 600 degs.
My flatbed trailers weigh 4,000lbs pulling them MT the truck runs fairly close to the same temps under same condictions the biggest difference is its faster on raising and slower on dropping the temps. Takes about 2.5 -3 minutes to drop to 450 degs.
I tow pretty much close and over 20,000lbs. This heavy towing the temps stay close and above 900 degs. The temps raise to 1,200+ degs very fast. It takes close to 4.5 minutes for the temp to drop to 450 degs.

They drop from what? What kind of driving? I have a farm thats down 10 miles of gravil road. When I got to the house my truck was at 300 degs, but of course for the last 2 miles 20 mph was the fastest you can run the road is that rough. A few months ago I bought another farm and moved. I still own the other farm I just rent the house out, but I have to keep reminding myself to wait to shut down here at the new house. Nooooo gravil. My wife loves it too.

If I drive from chico back home, 210 miles. It takes within 2-3 mins to drop to the 360 range. 3 mins would be a long time for me to wait.

What I was asking was when you put your truck in park what is your EGTS?

yes, make sure you put the truck in park or neutral, because if it is in gear and fighting the converter, the temps will not come down as far or as fast, and also the a/c OFF helps.
if i'm somewhere where it's possible, like home or my folks house, i will try to drive pretty easy the last few miles just to help, but i tend to pull the hood release a block or two from home, and hood will pop up to the catch, and it cools off quite a bit faster this way too,.
and sometimes when i get out, i will lift the hood all the way up and let it idle, cools off WAY faster this way.
i have a remote start alarm, so i trigger the "idle down" function before i pull the key out, and then after i've been in the house for a few minutes i will hit the button and it will shut the truck off for me, or if i forget, it will shut off in 25minutes by itself.
