Re: Mpg?
i will be running stock tires and rims. i'm not into the fancy stuff. i'm too old for that now.
i might consider an aftermarket exhaust if it will improve mileage but only for that reason.

another question. will the 2500 fit into a 7' garage door?
my 1500 fits with about 8" to spare.
my door is 83" counting the weatherstrip.

I don't know, I'm in the same delema as you. My 1500 just barely fits into my garage as it is, and the 2500 seem to sit a little higher so I'm not sure if it will make it or not?

Re: Mpg?
maybe i'll drop by the dealer tomorrow and measure theirs. if it don't fit then that will help narrow my choices.

Re: Mpg?
Hey guys, my neighbors got an '06 Dmax K2500HD and pullin a 20000 lb trailer he's gettin about 8-10 mpg. This seems kinda low. Hes also had a lot of trouble with injectors too. Three sets in 50000 miles, all under warranty. Hes really starting to hate this truck. I wanted to know if installing bigger exhaust and a different intake would help his mileage? If so how much? and what is causing his injectors to go bad?

Re: Mpg?
20,000 lbs??? I think 8-10 would be awesome pulling that weight....

If you mean 2000 then thats different.....

The injectors must be a fluke cause the 01-03 had the injector problems....id say he should be able to get a new truck after 3 sets.....has to be the engine....

Is he running any programmers....that may cause the injector problems....

Re: Mpg?
the truck is currently stock, I thought about putting bigger exhaust on it and an aftermarket intake setup. that should help his mileage i would think. I thought maybe too much backpressure would screw up his injectors, just a thought.
