Wow...dropping highway speed from 70 to 60 gives you 5-7 MPG better? I'd be after a set of 3.42 gears YESTERDAY.Yep I got a 06 and I love it, its got 128k on it now and only had a #8 injector replaced on it at around 23K I run 85% highway with it loaded near its gross weight most of the time and she gets 22-24 mpg at 60 mph. I found running above 60 you are just wasting fuel with this set up. I know if you run 70 your milage will be knocked down to 17-18 mpg and in my line of work fuel is my biggest expense I have.
set up is a, stock 3500 ext express with lly,4l85e, 3.73 limited slip
Ah my mistake, i was just going on what i had been told as i have yet to actually see a dmax powered van, there can be much room in there at all if they put all of that in there!intercooler?? do you mean charge air cooler ?? if you mean cac, then yes there is one between the a/c condensor and radiator.
