Miles per tank-the tale of two fuels

I've been reading a lot here about the Dodge 6.4 and CTD. Both look promising for what I need/want. Can I get some averages of those have a 2014/15 of each, of miles to the tank of just daily driving? I do a lot of highway driving of about 40K miles a year, so if I knew how many miles to the tank, I can get a rough estimate per fill up. Thanks

It is changing but for the most part I still have to travel further to find a station that is pumping diesel. I may have more range in theory with my diesel truck but that is offset by having to get fuel sooner to be sure I don't run out or have to make a 20 mile round trip detour to a truck stop.

Easiest to switch out the main fuel tank for a Titan that will hold 60 gallons of fuel and forget about it. For general driving the gas engine is the better choice. Diesel is good for trips of an hour or longer and when towing more than 10,000 lbs., otherwise it is not the way to go.

Not that that will prevent diesel owners from wanting to justify their purchase decision and pretend it was driven by logic and not emotion. I have a diesel pickup but I also have no illusions that it was the best buy or the most economical to own and operate.

Thanks for all the information. I've always been a Bow Tie man, but these new CTD are looking good. Just purchased a Jayco Jayflight 28BHBE and pulling it w/ a 2012 Suburban w/ towing package. It towed pretty good for the 35 mile ride home. No, to little sway, good, smooth acceleration and braking. Trailer sticker from dealer says 6911lbs, which includes AC and awning. We don't do dry camping, so just min weight for 4 people. The burb is due for tires in a little bit, so will be getting LT tires for better support. Lots of great info on here. Thanks for it all.

Well there is your problem!!
You need to be turning 2,200 rpm to hold 75 MPH in a head wind! :S

Got to love the damn Tractor motor!!!! :B

It is not as seriously unsafe as one may first think.

With today's smart cell phones, you can set it to take multiple photos at once. Then just keep adjusting the tilt on the phone, taking photos while keeping your eye on the road. Stop and examine the photos later once safely stopped. Throw away all the excess and you have the one as shown here, without being a danger to yourself or others on the road.

Really no big deal.

Should I dig out the one at 104mph?

That many miles a year, diesel is a no brainer. Plus you have the benefit of stress free towing.

40k miles per year? Get the diesel. It will be worth far more in 5 years at 200k than the Gasser. And when fuel prices go up, you'll be singing to the bank.

Also, if you don't need a truck, I highly recommend a Passat TDI. 700-900 miles per tank, 40-50mpg.

I get about 13-15 mpg during my commuting. 16-18 mpg straight hwy empty.

Both are 20-25% less than my last diesel.

I haven't really paid attention to the distance to empty reading when I fill up.
