The dealer where I took my truck used some dye and a black light to locate any leaks. Most were around the pan gasket but one was some gasket around the starter motor. All has been fine since I got it back from the dealer.
What kind of mileage do you guys get from your trucks? Mine is a crew cab 4X4 dually with the 4:30 gears and the factory Tow Boss package. It tows great, and the integrated tow command works better than any add on trailer brake system I've used, but I wonder if it's costing me much on the fuel economy with that gearing?
I have the Tow Boss + 4:30 gearing on a dually, crew cab, king ranch 4x4.
Highway, unloaded at 72mph - 15 mpg.
Mixed driving, unloaded: 14.1
Loaded with a Bigfoot 10.6 camper: 11 - 13.5 depending upon terrain, wind and how fast I drive.
Heavily loaded: 2880 lb trailer with - JD 3320, 300cx loader, rock bucket, rear blade, box blade, and 600 pounds of material in the bed: 11.3 @ 72mph.
For reference, the same camper on a SRW, crew cab, 4x4 with the 3:73 gearing would get 9.6 -13 depending upon driving conditions. With a heavy load, the truck with the 4:30 gears gets consistently better mileage.
However, unloaded the SRW 3:73 combination would get:
Up to 22 mpg at 55mph.
Average 16.6 mpg at 75mph
Average about 15.2 mpg in mixed driving.
The guy I sold the truck to put a different turbine in it, changed the exhaust system, and chipped it. In "mileage mode" he's averaging about 18.5 mpg in mixed driving and is getting about 21mpg at 75mph, unloaded on the highway.
