Gas mileage ?

All about towing and tow vehicles

Postby jss06 » Fri Aug 19, 2011 9:02 am

Drag is the biggest problem while towing.

Example.

Dodge Cummins 3500 pulling 7K lbs of car trailer and Jeep CJ that sits down nicely behind the truck I would average 15 to 16 MPG. Taking the extra 3 minutes to lay the CJs windshield flat on the hood would result in a 1.5 MPG difference.

Same truck pulling a 2K lb Travel trailer through New Mexico head winds only managed 11 MPG. This was the standard 8 foot wide by 7 feet tall front wall that acts as a sail.

Same truck pulling a 6x12 Uhaul that really tucked in nice behind the tailgate. It was probalby close to its max weight of 3K lbs of cargo. Pulled it full down to Houston from Dallas. Then empty back to Dallas from Houston. There was no noticable change in fuel economy. It was my normal empty highway average for the truck. About 23 MPG.

Keeping the trailer low and in the slipstream of the tow vehicle will put less stress on the vehicle than just lowering the weight. And results in much better fuel economy.

thus the teardrop design.

trailer low and in the slip stream of the tow veicle.

curved stream lined roof.

I built my tear deliberlty to not stick up higher than the roof of my ford exploreder.

slow.
Plans. there was supposed to be plans to be followed when I built this thing. Opps! AH, gee, tum,tee tum. I think I forgot about the plans 2 years ago. ------Tow vehicles, 1995 ford explore, 1994 ford ranger, 1993 ford F-150, 2009 4x9 Off road teardrop, on harbor freight greatly modified frame.

like a jon boat.

other than that I get the same milage as not pulling the teardrop.


the only real cure to worrys about gasoline is to get the dang goverment to lower the gas price to what there citizens and ecomomy can afford with out killing prudutivity and economic growth.

and untill that happens. Teardrops will be in demand.

The government does not set the price of gasoline. taxes and regulation do somewhat affect the price.

By "they" are you referring to the government making a point or the industry trying to influence our decisions?

I don't know the answer, but if I could only get into Area 51 I'm sure I could explain everything. :roll:

My 2005 Subaru Forester XT gets about 24-25 MPG with my normal mixed driving.

It gets 28-29 MPG on interstate, cruise-control long trip driving.

It gets 21-22 MPG on interstate, cruise-control long trip towing the teardrop.

It got 18 on my most recent trip to Lassen Volcanic National Park (elev 6000-8000 ft) with the car loaded to the roof and a 17 ft canoe on the roof.

The canoe and the large elevation gain (I live at sea level) seems to account for the difference.

I disagree. There is a reason or series of reasons all about supply and demand. We need to get smart and demand that drilling be allowed again in the Gulf. I know one person myself who is out of a job on a drilling platform in the Gulf. Restrictions need to be lifted and we need to start drilling for additional oil in the USA. That small percentage increase on the world market would be profound.

Then it is back to politics as being the reason after all!

In the UK 1 litre of petrol is about £0.47 a litre.
Of course once the government adds on its tax it becomes £1.31 a litre.
And they have the cheek to blame the markets for the price.
Thats £4.92 for a gallon. (or $8.02 a gallon) Apparently its more expensive in Germany. In venezuela I think, its about 2p a litre.
Thats why anything less than 35mpg gets a bit stressful for me! My current motor does 40mpg on a long run, about 25 in the city. Dunno yet what teardrop towing will do to that. :worship:

I just towed a 2012 Little Guy 5 Wide home to Ohio from Tallahassee, FL.... I tow with a 2012 Ford Focus Titanium, 4 cyl, 6 speed auto. Going down, cruise set at 70, not towing anything, I averaged 38-39 MPG.... coming back with the Little Guy empty, cruise set at 65 I averaged 29-29 MPG. So, yes, abut a 10 MPG drop seems to be right. Nothing changed but the trailer and speed, so this should be fairly accurate. :thinking:

I recently put a hitch on my 2013 Toyota Highlander specifically to tow my teardrop. It is a V6 with automatic and AWD. On previous trips the car averaged about 24 mpg.
Towing the teardrop three weeks ago I averaged about 19 mpg for nearly 2000 miles. A 5 mpg drop or about 20%.

When I made my 5,000 mile trip, I kept track of my mileage. My tow vehicle, a 2009 V6 Jeep Liberty, gets 19 mpg highway and 15 mpg city. With the trailer in tow, I lost just 4 mpg total; or, stated differently, I got 15 mpg overall, including both city and highway driving (but mostly highway driving).
