Denver to Kansas City and Back
Just traded my 04 2500HD LLY 38000 miles on a new 06 3500 LBZ Dually, drove from Denver to KC to drop off old truck and pick up new. 80 mph the whole way 570 miles.
Outbound trip in LLY 16.9 mpg overall
Return trip in LBZ 11-12 mpg for the first 300 miles, 15.3 mpg in the last 270.
Next day 100 miles of local driving 600 miles on odometer 55-65 mph, 15.9.
LLY 5 speed allison 80 mph, 2400 rpm
LBZ 6 speed allison 80 mph, 2050 rpm
Looking good to beat 04 mpg once fully broken in.
First 1000 miles and a COW...
Just returned from my first 1000 mile trip. 1500 miles on the engine now. Ran the AC the entire way, truck is stock. DIC read 11.2 MPG towing my loaded trailer ~9000lbs. Basically southern CA over the grapevine to monterey and back, AVG speed 55 to 60mph.
The MPG did drop a little when I smacked a cow returning over the grapevine!! :eek: Truck didn't get a scratch but the trailer has some damage. Cow didn't fare too well, but I was the second person to hit him... Shocks bottomed out but I don't "think" anything was damaged we hit hard, I'm going to the dealer this week to double check everything...
