Cummins engine gone, bed loaded with several hundred pounds of stuff still. Drove mostly flatland, no overdrive (still blown out). Motor screaming around 2,200-2,400 RPM.
490 miles, 25.23 gallons = 19.45 MPG


I'm surprised I was able to get that without overdrive.

None of that looks like 30 mpg

Nope. And the truck is now a dually with no overdrive, hauling a heavy load. I never claimed it ALWAYS gets 30 mpg, only empty (and with OD on flatland as a SRW truck) I'm sure you can see the excellent mileage it gets.

I also never claimed it gets 30 while towing or hauling a load, only empty, so take the time to read the words I have written. All my recent posts have been with a load, mostly in mountains with no overdrive.

I have a G56 on the way to replace the blowed up NV4500 and look forward to posting all my mileages, loaded and unloaded, once it has OD again.

Maybe it will never get 30 mpg again now that it's a 1 ton dually. I'm still thrilled with what it gets.

I never doubted a 12v cummins would get 20+ mpg, even 25 mpg. I still doubt you ever got 30 mpg unless you were going downhill.

I've seen 20+ out of my truck, running with the topper on, (good aero) doing the speed limit through ohio going 55-65 mph. I don't recall the exact mileage but it may have bee 22-23ish.

I got over 30 mpg leaving the mountains in west virgina, in fact my overhead was reading 38 mpg. Of course I was traveling 25-50 mph on a tight twisty downhill road where I doubt I hit the gas pedal for nearly the first 30 minutes.....

I know those cummins get great mileage, I just don't buy you consistently got 30 mpg unloaded. Did you get it once on a 45 mph trip on a flat road for 20 miles? sure, but I can't see a full tank of fuel averaging 30+ mpg in real world driving conditions.

I don't know what your truck is year/make/trans/ratio/drivetrain, so I don't know if you are making an accurate comparison. I don't have an overhead unit, so the only way I am able to calculate is by hand. As I said before, my truck is RARELY unloaded. I've only owned this truck since 1-1-12, and have seen a 30-31 MPG tank at least three times, always unloaded. Two of those tanks were flatland driving when I took the kids to Disney last month.

I have no reason to fudge any numbers and am frankly insulted that mostly you (honcho and boggin too) have made it your personal goal to publicly call me a liar, when you don't know me from jack, and don't know how seriouly I take my integrity.

I would never consider calling someone a liar without some hard hard facts first.

This thread was created for the purpose of information, partly to help people decide what to look for in a tow rig. I understand that you are probably angry with youself for your poor vehicle choices, but there is no reason to take out your frustrations on me.

LOL.

I'm plenty happy with the purchase I made, I have enjoyed my truck plenty. I am not taking my frustrations out on you, I'm one of 5 or 6 people in this thread alone who didn't believe your claim.

I'm not comparing my truck to yours, if you read the thread you'll see what I drive and some of the numbers i have seen. My overhead is not accurate, I was just pointing out what it read when I went downhill for nearly an hour.

17-18 is real world in my truck, I too very rarely drive it on a long trip empty since i have a car for trips like that, but I've seen as good as 20-23ish as I posted, but it's not a true consistent average, just like 30 mpg is not a true consistent and repeatable average for your truck.

keith dont take offended by the comments in here. if your taking comments made on a online forum to heart then you need to spend less time on here. youve been around plenty long enough to understand that this is a game and doesnt count for real world stuff.

how ever i just have a hard time believing your truck is getting that kind of mileage. what is so special about your truck that no one else's truck has that can pull those kind of hand calculated numbers?


sincerely,
boggin

I have thick skin for most stuff. You can call me fat, stupid, whatever. I have a problem with people calling me a liar. I have been around here for a long time, and those who know me know I pride myself on my honesty. Many times it has ruined a sale for me on some car or part, but I'd rather tell the truth.

As for consistancy, I drove my truck unloaded and back to Disney with the kids and wife. We averaged 28-31 MPG the ENTIRE trip. That was when the truck was SRW.

I just drove to Florida again (I'm here now) and you guys see the numbers I'm getting. My truck is now a dually, the entire trip was with a heavy load, and most of the trip was driven IN FOURTH GEAR!

And, as you can see, I still averaged 20 MPG!

It doesn't take a rocket scientist to figure out that my truck as a SRW, unloaded, and with working overdrive can get great mileage.

I have yet to run unloaded as a dually with working OD but will gladly post those numbers, whatever they are, when I know them.

you did not answer my question.

what is so special about your truck that allow's it to pull those number's that can't be accomplished by another truck?

I have no clue! I'm just reporting what MY truck gets! Maybe people with identical trucks to mine get the same, but none of those have chimed in yet.

2011 ccsb LML 6.5" bds lift with 37 bfg at's and a bullydog programmer

11mpg towing an enclosed 4 spot to the UP going 70-75 on the freeway and 60 the rest of the time. Last fill up was just over 13.5. Hoping to get 15-17 in the summer. I have seen over 20 on the DIC but I know that is not correct.

Towed my trail rig to wind rock a couple weeks ago. 01 dodge 2500 cummins 5speed 4x4, 295's, 3.55 gears, otherwise stock towing 5th wheel deckover trailer and exo'd toyota on 38's (~7k total)....filled up at home and drove to just north of lexington ky...13.6 mpg....filled up and drove to windrock then back out to the highway..14.8 mpg....filled up and drove to lima ohio...14.5 mpg....filled up and came home...13.4....ran 60-70+ the entire time.

Has anyone else noticed getting better mileage out of fuel you buy down south...i was pushing the truck harder towing in the mountains and gained just over a mpg , truck seemed to run better too. Is it just me or is the fuel different?

Default 2006 Dodge Ram 1500 Megacab

Here's my 1500 Megacab with a 5.7 Hemi.



I've had it for just a few weeks now. In town the mileage has been all over the place depending on my driving. I bought it because it's all 2500 underneath, same frame, axles, tranny, t-case, etc. The only difference is the springs in the rear of the 1500 are softer than a 2500.

2006 MegaCab
Base Curb Weight: 6482 lbs.
Max Payload: 2030 lbs.
Max Trailer: 7350 lbs.
5.7 Hemi
5 speed auto (45RFE)

NO LOAD
City - Heavy foot is about 10mpg's
Light Foot is about 11.5 mpg's

Hwy - Right around 14 mpg's

Towing jeep on single place trailer.
Jeep weight: 3685 - Weighed just recently
Trailer Weight: 2040 lbs.
Total: 5725 lbs. plus gear

Mileage was taken on a trip to Rausch Creek from Michigan usign the trucks computer.
Hwy: Ranged from 9 mpgs in the mountains to 11 on the flats. Overall mileage from start to finish was 9.9 mpgs
