Deisel vs. Gasoline

We bought a new 41 ft Redwood last fall (16,400 GVWR) and plan to start FTing next winter, after retirement. I'm planning to buy a Ram 3500 (or perhaps 4500) crew cab dually chassis, and put a hauler-style bed on it. I've been planning to fit the truck with the 6.7 L Cummins, but I have to wonder if the new 6.4 L Hemi might be sufficient for the job. We'll have a small car with us for day-to-day exploring, and plan to move around infrequently and seasonally - two months here, four months there - so there won't be a lot of annual mileage ; perhaps 12-15,000 a year for the tow vehicle, max. The $8K savings of the Hemi over the Cummins is tempting, but the extra torque and exhaust braking is equally desirable. Anyone with real-world experience out there who'd like to share the wisdom of your experience with us? (PS: my last rig was a Ford 350 dually with the 7.3 deisel, pulling a HR 30 ft TT, used for extended work trips - I'm a photographer. We have a lot of 3-6 month trips under our belt, and know the lifestyle we're about to move into.) Thanks in advance for sharing your knowledge and advise.

    Thanks for your viewpoint. That was my initial read as well, from my own experience, but since I have no experience with the new big gas hemi's, I thought I'd ask. Other people must be making the same inquiry.

    No, thanks, we won't be double towing the car - my wife will drive behind, or scout ahead.
  • Wow! Quick responses! I'd never even considered a gas engine until a friend pointed out that I might be overlooking a workable option - and he's a deisel mechanic! Even with a $130K + investment in the 5'er and truck, that $8K would buy a lot of solar panels. But it sounds like my initial judgement to go with the Cummins will be the correct path for a happier FT experience.

  • Personally for a 16,400# GVWR trailer I'd want the diesel. It's the right tool for the job. The new 6.7 L Cummins should run circles around the old 7.3 L.

    Just for perspective a 53' van semi trailer weights around 14,000# empty and a refrigerated is around 16,000# empty.

    Between the torque and engine braking, I'd go diesel.
  • I would go with the diesel every time. Btw that new Dodge Ram seems to be a helluva truck.
  • I would think that "saving" 8k after spending around 100k for a new 5'r and new truck is such a small percentage to be almost meaningless given the diesel will be the superior powertrain for your application.
  • I would recommend the diesel, you won't be disappointed. As far as the extra expense, you will recoup that when you sell or trade the truck in some day.
