I just got a new to me 2005 F350 CC PSD. Used it today on my first road trip pulling out new Wildcat 5th Wheel which weights dry a little over 10,000 lbs. Seems to pull real good. Slow starts, drive 60-65. I was really surprised with mileage (9.1 - 9.3), my 2003 Excursion got 12 - 12.5 pulling 8,000 lbs. Also engine would heat up often, once it even gave "Check engine temp" reading with a buzzer, also could only go 45-50 mph on I80 east of Winnemucca, NV.
Every 18 wheeler passed me except one, I did not want to race them, even if I could. Is this normal pulling over 10,000 lbs., 9 mpg, rea engine running hot but not really pushing it and seems to be a dog going up 6% grade? Sorry so long - just frustrated. Thanks - Dale

The truck is capable of pulling that weight easily. Are you loosing coolant? Does this only happen towing? Get a hold of a scan gauge/edge insight/cts something that will allow you to read codes and look at things like Engine oil temp, Engine coolant temp. Knowing these things are critical to owning a 6.0 and to your wallet! I personally would park the truck till I find out whats causing these issues.
I just returned yesterday from a trip to the eastern Sierras. Temps on 395 out of Bishop were 97 degrees and my 31 ' fifth wheel is 11,000 lbs. dry. ECT on the largest grade, 6% for 8 miles, never got over 227 degrees and I was in tow/haul, cruise set at 60 mph. On level ground the ect/eot deltas fluctuated between 4 and 8 degrees. Had a 25 to 30 mile per hour head wind and got just over 11 mpg.

My 2005 CC 350 Gets about 11.5 on the hills about 13 on the flats. We tow a 5vr that is in the 11k area. Get gauges! You must have them especially towing. Check coolant level, check for benting/puking at your degass bottle.

One other thought - If your EOT (engine oil temp) is getting up to 235 degrees then the engine protects itself by de-fuelling .... makes its performance really weak.
As mentioned above - you can only read EOT using something plugged into the OBD2 port (Scangauge or similar).
If your EOT is particularly high vs coolant temp then you (like all the rest of us) will need a coolant flush and a new oil cooler.
8000lbs toy hauler 06 F350 DRW. 9 miles to the gallon. Up or down mountains, makes no difference. EOT/ECT delta never more than 12*. You don't buy them for mileage. you buy them to work.

If you're going to tow with a 6.0L, you need gauges. It's to the point where there almost a requirement to get help from people on here, because they narrow down general issues like "the truck is too hot and losing power" to a specific system on the truck.
This thing will get you coolant temp, oil temp, trans temp, digital boost, and a bunch of 6.0L specific PIDs that you'll eventually need. Best product out from a $$$ perspective, there are more options if you want to pay more: http://www.amazon.com/ScanGauge-Auto.../dp/B000AAMY86
You have to add sending units for fuel pressure, Exhaust Gas temps (EGT/ pyro), and mechanical boost: I use these, but there are several other options from AutoMeter, Glowshift, etc. ISSPRO EV2 Gauges - Black Face, Red Pointer, Black Bezel

Having the ability to monitor your engine is going to save you big bucks. It should be number one on your priority list. No bull.

Sorry to hear your troubles but pulling the above few lines from your post sounds like you may have bought someones elses problem. You must get your hands on one of the recommended electronic gauges to help you see exactly what you got .... and to help folks on here help you.
Do not ignore overheating warnings on this engine ... it will get real costly real quick.
Did you get any warranty on your purchase or was it an 'as-is' sale?
