Fuel mileage pulling 305v12

[MOZDZL]

Just curious what king of mileage people seeing pulling these toy haulers I have a 2004.5 dodge cummins 2500

[Adh203]

I get 12 mpg towing empty and 10.5 mpg loaded with two Harley dressers. That is at 70 mph with a 2013 f350 dually 6.7 diesel. I hope this helps

Thanks how are you liking your 305v12 ?

I don't have the v12 but I have the x12. I've been on two trips thus far. One was about 1400 miles round trip and one shorter one of about 400 miles round trip.

I have a 2007 Dodge Ram 2500 5.9L truck. The only mod I have is a Smarty Jr. Going strictly by the overhead readout. With 3 sport bikes and a dirtbike, along with 3 passengers, full water, full fuel in the trailer and a lot of race gear, I have found the following.

Wind is your enemy, maybe on a v-nose it will not be as pronounced but when we hit a head wind of about 15-20 mph it robbed us of 1.5-2mpg.

Going 60-65 I was consistently over 12mpg, generally about 12.3ish depending on the amount of hills.

Going 65-70 I would get mid 11's

Going 70-75 would be in the high 9's.

I had 700 miles to play around all highway so I would set the cruise control for an hour and check the results.

I'm getting 8 mpg pulling the 27hfs with a Yukon XL Denali. The fuel milage sucks, but it's more practical than buying a big diesel just to pull the toy hauler. I pull the 27hfs with my every day driver.

I get about 10.5 to 12.5 trailer the trailer weight is about 13000 pounds I went to Texas and back about 1500 miles each way. I am trying a new fuel additive and my mpg went up about 1 mpg the best I could tell

Heading to Louisiana on Tuesday. I have the new 305 V12, my puller is a 2008 6.7 l dodge. I will let you know Tuesday when we stop in Tennessee.

gonna go out on a limb, and there is a chance i'm wrong, but 8mpg with that vehicle and toy hauler is VERY optimistic.

I have way over 100k miles towing a 24x8.5 race trailer that weighs about the same as my 2013 xlr27hfs.. but the xlr is taller. I have a 2005 diesel excursion in great shape. i tow all over the flat as a pancake state of Florida (almost zero hills/incline). I RARELY ever go above 70 mph in the interstate. the best i do is 11mpG on the highway. If i have to drive around the city a bunch with the trailer, it's worse. With the xlr27hfs?? it goes down to 10mpg unless i back er down to 65mph.

I had a lincoln navigator years back pulling a 7x16 dual axle trailer (weighed way less than a xlr27hfs ) .. i got SIX-SEVEN mpg with that thing even at 65-70mph .. LOL !

I would take some more readings towing the xlr in your Dinali but be sure you reset the thing from any driving prior to towing.. or better yet, be sure your speedometer is correct, and do the math the next time you fill up

Maybe apples & oranges here our 2013 Puma Unleashed 35.5' TH 5th wheel with my 05 Dodge Duelly Cummins I get 12 mpg flat ground.

Our old 06 25' Puma 5th wheel weighed about 8K (4K less than the new one) pulled it with an 03 SRW Dodge with Hemi got 8mpg on a good day.

Overall the Duelly gets 4-8mpg better than the SRW gas

60-63 mph pulling a 13000 lbs tractor and trailer using cruise control got me 2-3 mpg better than using my foot

I got 40x12. Gross weight is 18000. I pull it with 2011 F350 dually. 6.7 diesel. 70-75 mph around 9 mpg. Can't tell about slower. Don't go slower.

That's what I got the when towing it home from Michigan and when towing it to a race from Ohio to Ky over the winter. It seemed to average 7.6-8 mpg each time I towed.

I was not running the air conditioner, which I'm sure will make a difference, and I also was not going over 60-65 mph.

I'll get some better readings over the next few weeks and post an update. Anytime I tow anything at all I reset the fuel MPG to see what I get. I'll take 7.5-8 mpg any day, so hopefully it stays there.

Also, the dealer asked what I get everyday driving and I told him around 15mpg... to which he replied, well, you can count on getting half of that towing this thing. Thus far, it looks as though he was right on the money. And, he was towing a large race trailer with a 2007 Yukon Denali as well.

i could see that mpg driving 60-65mph. that i suspect is realistic. I see a significant difference as you get closer to 70mph and above. mpg starts to drop even with my diesel.

60 mph 9 mpg, 12000 lbs in the 305v12. 65-70mph 8 mpg. Circleville Ohio to Buccaneer State Park in Waveland Ms
