I had GM stuff before and LOVED it!! I used a 2000 2wd 5.3L first, then a 2001 4wd 2500HD Sierra with the 6.0L, then the 2001 Dodge 4wd diesel, and now the 2006 4wd Mega cab diesel dually. I converted after going through a motor on the Sierra and borrowing the '01 Dodge from a friend that was selling it.....I was hooked on the way the diesel towed compared to the gas motors. Also I knew if I was going to have a diesel it could not have an automatic. When your making power and at a high GCVW on long hauls it just would kill you in break downs and maint. Thats the ONLY thing I really think you need in a tow rig with power...When I decided I needed a bigger truck I wanted a 2wd, I went looking at the Duramaxs, and the Megacabs. I ended up with the 4wd Mega cab as that was all I could find at the time. I'm glad I got it living around here I would have HATED not having the 4wd. Even though it lowers the tow rating IMO in this reigon without it your in trouble....I miss my GM trucks, in all honesty I liked the ride and interiors. Lots of people don't but I find myself missing alot of features they had. i just felt like I fit better in the trucks. Might just be that brand loyalty coming through....
What you got:2006 Dodge Mega cab dually
What trans? 6-speed manual
4x4? Hell yea
Ever really needed 4x4? Yup
Carry a camper? not so much
How much total towing weight? I would say about 10-20K
Speed up Snoqualmie or White pass loaded? While keeping the EGTs in check, around 70-75.
Avg empty fuel economy empty? Loaded? Empty- 16 -20, depending on my right foot. Loaded, 8-12
Also can you throw in a little about what you dislike about your current tow rig? I like the short bed but sometimes I would like a full 8 feet, not all the time just SOME of the time, and auto would be nice for driving everyday also...
