Drove up to fairbanks yesterday and picked up a parts truck from Jamierayo. I was running with an empty trailerand an extra set of tiresandwheels to put on the truck. Ran about as close to 65 as I could most of the way saw 13psi boost a few times and had a little tailwind avg 13.6 mpg The first 125 miles I went from 250' elevation to about 3500' fairly gradually. Then just before Fairbanks there's some pretty good hills I'd guess a couple of 6% fairly long too. Got the truck stripped of the parts Jamie wanted to keep loaded up and headed home. So I hit the hills just outside Fairbanks and started up the first and longest grade was doing pretty good until the temps started getting up there. Ended up in 2nd and temps were about 220* but the egts were only 700*. Thought I was going to have to stop but I made it. And (this is for you Matt) no fan clutch engagement. So I guess I'll be looking into the fan clutch mod. After I got thru the hills it was pretty flat roads but I pickked up a pretty good headwind (front moving in). It got so bad that I was running about 57 mph and had 900* egts and anymore throttle unlocked the convertor. I'm glad it wasn't 80* or I would have over heated. Saw a wind sock it was standing stright out which is 40knots IIRC. Finally got thru the worst of that and then I could cruise at 63 with about 6-700 egt and about 4-5 psi boost. Made it home about 11pm.
 
Funny how you need a working fan even in snow...
 
Even my dealership purchased OEM replacement fan clutch wouldn't kick on until in cab gauge red 220-230.

Imagine how hard you would have pushed it if you thought the dangerzone really was at 260.
 
Do you take the east road or west road to fairbanks? West road has some real long grades near mckinley. If you took the west road did you stop at skinny dicks halfway inn?

Trailer I'm guessing weighed about 1500 and the truck was a 1ton crew cab minus engine tranny (still had transfer case) grill core support pass side fender both front doors and seats. Maybe 4000 so a total of 5000-6000

west road which is the Parks hiway #3 no I didn't stop at skinny dicks although it sounds like you have
 
My fan allways runs,prob no good for milage but i never see temps go beyond 195(got the colder T-stats)No AC cooler either ,hills or flat,been pulling upwards of 13000 lbs.Tranny temps only 130 for high.
I got to watch the EGT's though,tends to redline towards the end of a long steep slope.

maybe yours just engages really early but i have a 350 that the fan runs all the time, and it was beacouse the bearing in the clutch was froze, the fan ended up spinning off and going through the radiator:nonod:
