Fuel Mileage with TC

[lap527]

Yahoo! On the last trip we got 14.8 MPG! Oh man, it was so easy pulling into Wally World to buy my bicycle a light. We were not dragging boat nor bike trailer. If my mind serves me right we got a little over 11 when we took the boat on a previous trip. We shall find out real soon about the bike trailer as we will be towing it on a trip. We enjoyed our fiver but downsizing to the TC has been a good move for us.

Just got back from a trip with the camper and boat. I got 12.5 there and back. 2013 chevrolet silverado 3500 srw 6.6 duramax with a 2008 lance 815 and a 2010 crestliner superhawk 1700 which weighs about 3000 lbs. There was both interstate and country back road driving.

Cannot compare with so many differences in load carried, speeds driven, elevation gains, and even wind. On a trip last year cover 3000 plus miles up to Yellowstone and back through Utah and into California I averaged 13.5 MPG with a diesel and with a 3700 lb. load in the bed. Recent trip through eastern sierras up Hwy 395 with 4000 lb. load in the bed and dealing with a lot more wind and more elevation gain in total the MPG was 11.1 for the 1400 mile trip.

Wind is the biggest factor. On legs I drive frequently, if there is a 15 MPH head or cross wind the truck's gas mileage is reduced by 25%.

With the high price for diesel fuel (usually about the same or more than premium) and the more expensive initial cost and maintenance costs one should not go with a diesel engine in the misguided belief that they will save money doing so.

Oh now come on.... one can't put a price on having all that extra torque. 😉

That is really the main reason to go diesel, the extra power. The argument of cost savings doesn't really stand up in my experience. 😛

That would really depend on how long one intends to keep there vehicle,most get a new one every few years. If you intend on keeping your vehicle for for a long period of time the diesel is going to last much longer. If you are driving a gas truck, to go the same speed as a diesel you are going to be turning at a much higher RPM than a diesel to obtain the same result. That means the engine is going to go a lot "farther" rotation wise. But you are right the torque is really nice especially when going up long steep grades like the one from Calif. to Oregon>

On flat & level at 55 mph we get 15.2mpg.
At 60 mph we get 14.2mpg
at 65 mph we get 13.4 mpg
at 70 mph we get 11.2 mpg
We very seldom go over 60 mph

I'm averaging 13 MPGs at 65 MPH.

17 with our Bronco on the back and 14 to 15 with our Sunline 30 foot in tow.. The 6.7 does way better than the 5.4 gas we had...

[gdavidg]

drove same trip two weekends in a row. about 250 miles round trip, 4000 foot climb in 60 miles down hill to 1500 feet at other end. Hand calculated 10.6 mpg trip one (lielage meter showed 11.4), 11.2 hand calc second trip (11.7 CAR computer)

2010 CTD AT, Lance 950S, say 4000 pounds, no trailer.

In july going to the Wallowas pulling a drift boat and camper but more stuff. will report after.

Traveling in the White Mountain region New Hampshire with our Ford Powerstroke 6.0 liter, DRW and 4.1 ratio.

I made 12.75 mpg average, loaded with a Northern Lite classic 9.6.

For a truck like this, i think it's not bad for mountain traveling

This thread, people should state their diff ratio, as with previous 2011 Chev 2500 diesel was 3.73 and new 2012 Ram is 4.1, 20% difference, so lower fuel consumption.

4.10s, used to get 8-9 mpg consistently in the days before Ethanol.

I think that if any truck gets up to 15mpg with a camper I would be in heaven! ..... however....

1996 Extended cab one ton dually w/ 7.4 v8 and 4:10 diff. 9'10" camper around 3,500-4,000lbs, depending on people and supplies.

I average 8.5-9.5mpg. I CAN get around 10-10.5 if I keep it under 60mph, which I rarely do on the freeways here in CA. Of course I didn't get the truck for economy, THAT's for sure! 😉 I just save up and pay the price!

I find that really hard to believe.

Yes, it is possible going downhill with a tail wind, with the moon and stars all being in perfect alignment to the North Pole.
