Do the diesels typically average 10mpg loaded with a trailer and does running 75-80mph really affect the mileage, it sure does on a gas Suburban.
I get 12.2mpg with my Duramax loaded running 65 to 68 hope to be up around 13mpg this year with my air box mod. yes going 75-80 will affect your mileage. on a side note I get 19mpg running 68 empty.

I know the older Dodge and Ford trucks were really loud, after just spending the weekend in a friends Chev Duramax I noticed the fan is quite loud from the interior and seemed to kick in and out alot. there is a fix for the fan running all the time. (the fan will kill your mileage) he must have an LLY motor.
