Ram 6.4 Hemi & Cummins Test Drive

I'm currently in an 06 Duramax and it's been a great truck but as the miles tick upward I'm thinking of something new.

So, I just drove both the Ram 2500 6.4 and the 2500 Cummins back to back, same road/route.

Overall, both are great trucks. In the end I actually like the 6.4 better as a daily driver and am hopeful it will do okay towing my 8500lb TT. If I towed more I'd probably go for the Cummins.

The 6.4 was more "snappy" off the line and had good strong acceleration right up to 60. IMO that 6.4 is a really nice engine. The Cummins of course is no slouch but it just has more of a diesel feel to it. Up the hills of course the Cummins had way more punch.

The new rear coil springs are nice but the ride is still stiff and shaky at times as with any 3/4 ton truck. The ride was definitely better than my current Duramax but I'm trying to figure how much of that is just because my truck is 8 years old and has 140K on the clock??

I made it out without buying (salesman holding me at the ankles as I tried to walk away :) ). I'm pretty strongly considering it. I may make a run at selling my Duramax private party rather than taking the bath at trade in. LOL.... they offered me $14,500 for my trade then quickly upped it to 20K when I laughed at them. From checking local prices I'm thinking I can get close to 25K

Anyhow, I'm not much of a brand loyalist but can tell you Ram is turning out some nice trucks. I think I test drove one probably 10 years ago but have otherwise never been too much of a fan. I've previously owned Ford, Toyota, Nissan and my current Chevy. I guess it's time to complete the circuit :)

    Were the rear tires inflated to max psi on the Cummins?? Could make a difference of how it rode down the rode


    They both had the monitoring system on the dash and as I scrolled through I remember them all having all 4 tires in the mid 70s. I remember thinking it was odd the fronts were almost to max psi. I didn't check the door sticker but on my Duramax it says 55 for the front. They must just fill them all up all the way at the factory.

    The 6.4 should have zero problems towing 8500 lbs.

    As far as 3/4 ton truck ride I hoped that the coil spring + air bag would have helped alot.

    Are air bags a standard feature?

    No, the air suspension is an option, I believe about $1500-2000.

  • Thanks for the post. I've been wondering how those two engines compare.
    As for your truck. I'd be really disappointed if you could get an other 140,000 miles of it. My '05 has almost 180,000 trouble free miles and I hope to see at least 300,000 before I get rid of it.
  • If I was towing 8500 pounds I would go gas. They both are nice trucks.

    Where I used to work had a 2006 or so 2500hd duramax crew cab 4x4 that was the best riding 3/4 ton I have ever been in. My 2012 2500hd rides pretty rough, wish it was smoother.
