All - trading my 2005 F250 6L for a 2007 Megacab...they have the 5.9 and the 6.7 available. Which would you get...adv/disadv? What kind of mileage can I expect with each...both are autos.
Does Dodge plan on coming out with a longer bed for the Megacabs any time soon? Thanks.

 

if you can get a 5.9L I would get that one. very few problems and has been a proven platform for many years. the 6.7L has some issues but Dodge is working through them and getting things figured out.

as far as a factory long bed on the mega cab, thats not going to happen. now you can take the truck to a place in texas that will extend the frame for the long bed

I believe the site is long bed mega cab.com

fuel mileage, you could expect 15-17 off the lot, but after 10K the mileage will go up and you may be able to see upwards of 19mpg.

 

If you can get your hands on a 5.9 get that. We had a 5.9 & a 6.7 for a while. The 6.7 was getting 3-5 mpg WORSE milage than the 5.9 & it was a smaller truck.

 

I've had both a 5.9L and a 6.7L within the last year. I'm driving a 6.7L (nuff said).

Seriously, aside from lower fuel mileage, the 6.7L with the 6 speed auto is a much better combo (IMO). Let the flaming begin!

 

OK!!!

 

5.9 5.9 5.9... tried and true...

 

oops, forgot to mention, my truck as it sits, I can squeeze 18 mpg out of it. I am damn curious to see what it'd do with stock or near stock tires on it.

 

The 5.9 should give you better MPG. I'm only getting about 15-16 with my 6.7. The 6.7 is very quiet, smooth, and powerful. You will probably be happy with either choice.

 

The 5.9 does not have all of the new EPA cr@p and will run on LSD and ULSD fuel.

 

Either one will be an improvement for you, it was for me after trading in my '04 F250. I am partial to the 5.9 b/c it is much more simple than the 6.0 or the 6.7.
