Double kilotank: 2,009.6 mi on one 35 gal tank ('07 Dodge Ram 2500 quad cab)

At this rate I don't think it'll be too surprising if you manage 75 MPG in a trip, Maybe even in a tank.

that would be quite the increase lol. 75mpg on 35 gallons would be 2625 miles In order to break the unofficial world record for one tank (2,254.5 miles) he would need to hit 64.5mpg. I think this would take perfect weather conditions and probably more modifications since his best trip was 68mpg. If anyone can do it though it's probably DD.

Damn good job.

Exceptional accomplishment and sets a high goal for us to try for. Is there a posting with a photo of your truck with mods? I'd like to see what it looks like.

Props to Diesel Dave for exemplary performance.

Much of it is due to his recognition of the importance of road speed in the road load equation.

Aero drag HP goes up with the cube of road speed.
Everything else is proportional to road speed.

Few people (me included) can keep their speed down like DD.

65 MPG probably isn't too far off with what Diesel Dave has planned. I wonder what's in store?

If he can get such high MPG in a truck I imagine he'd be able to get 30+ MPG out of a car such as a 1996 Roadmaster Wagon (Stock photo):



Well, It's a gas car. But still - I can get 30 MPG HWY in my Dad's 2000 Caravan without as many mods as Dave has done to his truck and the Roadmaster has faster acceleration.

EDIT: "I can get 30 MPG HWY In my Dad's caravan"; Yes, With wonky readings as according to what I said here back when I posted it. I haven't gone above 27 in a whole tank yet, But I do believe I can get more than 30 in the caravan.

At this point, it looks pretty stock from the outside. The exception is the recently-added side skirts:

The only other thing you can really see is the grill block if you look close:

Is that a soft tonneau cover I see on the bed. A flat tonneau was worth 1.5 MPG for me.

Yeah it's a soft tonneau.
