Hey this is my kind of thread!
I have a 2008 Ford F-450 crewcab 4x4.
Mods- S&B cold air intake, Spartan DashDaq Tuner, def delete. MBRP full 3" intake pipe, 93 gallon Aux tank/tool box combo. B&W turn over ball with companion fifthwheel. I run the truck on the mild 210 tune, best guess is around 500 to 550 horsepower and around 1200 ft lb of torque. It has a 4.88 gear so around 85 mph is all I'll push it.
Around town it's gets 14.5 mpg, highway 17 mpg. And towing the 5er it's close to 11.5, I tow around 75 mph on cruise. Before I tuned and did the delete it got around 12 mpg on the highway, 9 mpg in the city and 10 mpg towing. My DW calls it the Beast.
My Prior truck was a 2002 F-250 4x4 with the 7.3 Powerstroke, I loved that truck, it 275, 000 miles when I traded it in on this truck, the motor it in was strong but the rest of the truck was getting some age on it. It handle our old 28 ft 5er good, but I didn't feel good hooking up to a 14,000 lb 43 ft 5er and striking out with it.
They were talking about this on the other thread, but I wanted to add it on here...
Diesel fuel prices. I buy my fuel across the stateline from my house in the great state of Mississippi (Tiggerdad's stomping ground) it's cheaper there, just checked my Gas Buddy app, It's 1.79 for Diesel. Good for folks traveling and the truckers and farmers but bad for us working in the oilfield.
