Diesel

I have a 2001 Yukon XL, ton, 8100 engine, a 373 rear end pulling a 28 International CCD. It does a wonderful job and I get about 8.6 MPG when towing and 12 to 13 when not. Mountain pulling is good considering 373 rear end, most at 55 mph.

I have been talking to a lot of people with diesels on this 8 week trip.

They have all said that they would purchase them again, GMC/Chevrolet, Ford and Dodge.

I have heard mileage from 11 to 15 towing 5th wheels and 11 to 22 when not towing.

I was wondering if anyone out there has a diesel. Which brand and configuration? What kind of mileage you getting?

Does it make you trailer smell when towing?

Blessings,

Fred

Fred,
We use a 3/4 ton GMC Suburban diesel when towing and depending on the layout of the land, average 13mpg. Mileage without the 29' A/S in tow is 19-21 mph.
Even tho 3.73 rear works, I believe the 4.10 would be better with my setup.
Would I ever go to gas?
Let me think abt that and, get back to you in about 10 years...lol
OH YA, about the question of OF SMELL..
I assume you're talking interior of the unit..
Nope...not once has that been an issue..
ciao

Fred ...

Welcome to the Forum.

I have been driving my Ford diesel for 18 months ... it has 24,000 total miles ... 6,175 of those are towing miles.

Since day one I have kept records ... I'm getting 13.62 MPG overall ... best mileage driving is 17.213 MPG ... best mileage towing is 12.576 MPG ... worst mileage towing was 10.42 MPG.

I usually tow in the 60-65 MPH range ... the AC is always on.

GM, Dodge and Ford all make very good diesel trucks ... I chose the Ford because it was right for me ... and I got an employee discount before it was common.

My trailer does not smell.

Mileage? I got your stickin' mileage..... RIGHT here!

Hello all -

Went thru all the gas receipts and afinally tallied them from 0 to miles 4236.4 and end of trip. Got 10.76 MPG as a HIGH and 10.278mpg as a low. Wind, sighseeing, getting away from inlaws all either encouraged or discouracged the way the needle worked.....

It costs what it costs, to get to see what you and I want to go see. Toss in a few kids and all bets are off and "Damnthe Topedos as far as gas cost goes" we gotta pay what ever we gotta pay; `lternative is to see home and think about what might have been if you had gone.

Life is to short, go and live it like it is meant to done.

Cool Love my Duramax!

We have been on several trips of 100+ miles. The best mileage when towing our trailer was pulling it home from the dealer in April, no AC on, 58 mph average speed on a US highway, 14.8 mpg for the 150 mile trip. The worst mpg towing was a trip to Wisconsin into a 20 to 30 mph headwind, speeds were 65 mph, 11.9 mpg. Other trips have been in the 12.8 to 14 mpg range, dependent on winds and speed.

I would definitely get another GM Duramax powered vehicle .

12.9-15.3 mpg towing the Airstream. 16-21 mpg solo, depending on driving conditions and the weight of my foot! I would buy another that is for sure. As long as diesel is less than a dollar a gallon more than regular, you do come out slightly ahead in cost per mile.

Durmax, for sure

I bought a 28' Classic at the Springfield International and got just a smidgeon under 15 mpg towing from Springfield, MO to Austin, TX. I tow at 60 mph.

Even with high diesel prices, it is far cheaper to tow with diesel than with gas. I have a 30 gallon in-bed tank for a total of 56 gallons. That allows me to buy diesel where the prices are best. For instance, I towed from Springfield to Corsicana, TX without need for refuel and then found diesel at $2.089/gallon. I could have easily gone on to the Flying-J at Waco with the fuel on board.

I lose about 1 mpg towing at 65 and gain about 1 mpg when in a caravan at 55.

The diesel cost an extra $4000 list with rebates, but I'll get that and more back if and when I ever trade. In the mean time, towing with the diesel is sheer pleasure.

Thumbs up Anyone good at math?

Has anyone done the math? I'm not good at that!

Diesel vs. gas.

Say - Diesel engine costs $5,000.00 more than gas ...
Say - 15,000 miles / year use
Say - gas consumption 10.8 towing / 13.6 light
Say - diesel consumption 12.5 towing / 16 light
Say - towing = 25% of use
Say - Diesel cost $ .20 above gas cost / per gallon

Or substute some realistic numbers of your own.

Calculate 5 year use before trade ...

Disregard extra cost of maintence, oil changes etc.

What does that wash out in comparison?

Just curious - absolutely do not want to start an argument. The extra $5K at the start is a good kick in the beginning.

Personally I have a V-10 and love it. My 5th one. 4 Excursions & 1 F-250.

I'm like AXEL, it costs what it costs.

I also put 238,000 great miles on a 1983 3/4 Suburban 6.2 diesel 4X4 and would probably would still have it if the body didn't rot away.

Have a new Duramax Crew Cab with less than 1000 miles. I go out on the Interstate, get up to speed (64mph), put it in cruise and reset the MPG gauge. this way I get a MPG without the start and stop. While I've only gone 60 miles or so the read out is 22 mpg in slightly rolling terrain, otherwise I'm getting 16 mpg overall back and forth to the office about 10 miles. Kept my 96 K1500 for 9 years and 97,000. I was going to step up next year put the deal was too good. It's for sale. No one trades a diesel after 5 years, it's just breaking in. Even the commissioner of taste and decorem likes it. And the power is not to be believed.

I heard a rumor that home heating oil in the northeast is the same stuff as deisel fuel.

Diesel Power & Mileage

I tow my 30' Escella with a 6.0 Powerstroke 2WD Ford F250 crewcab. My truck has 11,500 miles on it, nearly 5,000 of that towing.

PLENTY of power and my truck is absolutely stock. My rig will top a 6-7% grade at 55-60 MPH usually with power to spare.

My best mileage has been 17.8 running empty at 72-75 MPH on the highway, I average 15 MPG commuting on a combination of semi-rural roads, city streets, and a bit of interstate. My towing mileage averages about 12.5. My worst was 10.1 fighting a 40-50 MPH headwind @ 65 MPH, my best was 14.0 on I-5 in CA running 60 MPH. I tow at 65 MPH when not in CA, 60 in CA.

No evidence in or on the trailer that I use a diesel powered tow vehicle.

Personally I wouldn't swap out a gas powered tow vehicle just to get a diesel. If your Suburban isn't working out for you and you want a new TV than by all means get a diesel. The only downside is initial purchase cost and the hassel of finding decently priced fuel.

In all these so called "life cycle cost" comparisons it seems that everyone overlooks the difference between "maintenance" of a diesel verses a gas motor and over time it can be substantial. however the diesels "pull real nice"
