Gas Mileage Survey

August 2013 - bought a '93 13 ft. Scamp.
August - Present - have been rehabbing it.
Present - have taken it one several 'shake-down' trips in preparation for a 2 week trip in June to UT/AZ.

Impressions: She pulls nice! But boy does the gas mileage suffer.

So, I would like to ask folks to take the following survey which I hope will supply me with some good information. Please copy and paste the categories into your response and fill in behind them.

TOW VEHICLE:
MAKE:
MODEL:
YEAR:
CYLINDERS:
MPG AT 65MPH TOWING NOTHING:

FIBERGLASS RV:
MAKE:
LENGTH:
YEAR:
APPROXIMATE WEIGHT:

IN TOW:
MPG AT 65MPH WHILE TOWING:
YOUR OPTIMAL KNOWN MPH FOR BEST MPG?
HAVE YOU DOWN ANYTHING ELSE TO INCREASE MPG? (EXAMPLE: WIND FAIRING ON TOW VEHICLE.) IF SO, WHAT?

Thanks All. I am hoping to learn a lot by this! David

There's a huge thread on this in the archives that you may find informative.

So, what's your gas mileage?

Because there are so many combinations of TV's, trailers and driving styles, as well as an occasional bit of padding, these surveys seldom turn up any accurate or useful information. If you can specify your particular Tow Vehicle, trailer and trailer weight, those with same are more apt to add in information that is useful.

Some Rules of Thumb that have come out....

1. Smaller & High MPG vehicles will have a greater reduction in MPG's than bigger vehicles.
2. Anything over about a 33% reduction can usually be improved upon.
3. Driving into the wind can increase fuel consumption big time
4. The "Sweet Spot" for towing is between 55-60. Above that wind resistance begins to play a major role.
5. Be willing to slow down/downshift for hills. You will get there.
6. Ya gotta drive like you are in a MPG contest

TOW VEHICLE:
• MAKE:Subaru
• MODEL: Outback
• YEAR:2014
• CYLINDERS:4 cvt
• MPG AT 65MPH TOWING NOTHING: 32

FIBERGLASS RV:
• MAKE: scamp oak
• LENGTH:13
• YEAR:2014
• APPROXIMATE WEIGHT: 1800

IN TOW:
• MPG AT 65MPH WHILE TOWING: 15
• YOUR OPTIMAL KNOWN MPH FOR BEST MPG? ?
• HAVE YOU DONE ANYTHING ELSE TO INCREASE MPG? (EXAMPLE: WIND FAIRING ON TOW VEHICLE.) IF SO, WHAT? no

I think the Subaru 4 cyl and the cvt are a bad combination for towing. I wish I had gone with the 6 cyl. On the other hand I towed a much heavier 16 foot Scamp with a 4 cylinder Saturn Vue cvt and always got 18 - 20 mpg. Go figure. I expected more from the Subaru.

TOW VEHICLE:
• MAKE: toyota
• MODEL: highlander
• YEAR:2008
• CYLINDERS: 6
• MPG AT 65MPH TOWING NOTHING: 23

FIBERGLASS RV:
• MAKE: burro (former trailer)
• LENGTH: 17'
• YEAR: 1991
• APPROXIMATE WEIGHT:2100 lb

IN TOW:
• MPG AT 65MPH WHILE TOWING: 13
• YOUR OPTIMAL KNOWN MPH FOR BEST MPG? 14 mpg @ 60 mph
• HAVE YOU DOWN ANYTHING ELSE TO INCREASE MPG? (EXAMPLE: WIND FAIRING ON TOW VEHICLE.) IF SO, WHAT? just slow down, the best way to save.

I have seen some 4 cylinder stick shift Hondas and Toyotas getting from 18 to 22 mpg with a 13'er. People with small diesels (Jetta, Passat, maybe Chevy Cruze) seem to get high 20s, but they are towing over their rated capacity (usually 1000 lb). The 3L diesel in the Grand Cherokee should get low 20s, but I have no data. Other than those types of vehicles, I think you will find that 15-17 mpg is very, very common among those who tow a 13'.

The best thing to do is relax and forget about the mpg's. Go camping, enjoy yourself, enjoy the trailer. Next time you need a replacement vehicle, you can decide if you want to shoot for one of the above types (or something new might have come out by then) for greater fuel economy. But trading vehicles when you don't need to, just to get a couple extra mpg's, will almost always cost more than the fuel saved.

Sorry, I have nothing to offer. I don't tow at 65mph. The sweet spot for my tug/tow combo is 57 mph... on the flats. I'd rather leave earlier, drive slower and keep the bucks in my pocket than running it through the gas tank. YMMV

Yup the form may need a little editing due to the fact it is illegal to tow at 65 mph in some states & provinces.

We are with Donna and Carol. We have never towed at 65. Our first set of tires got replaced because of age not wear. We never had a blowout.

Our old Honda Ody got a consistent 17.5 mpg average on our 3-5000 mile trips. Trailer weighs 1640. Drive 55-60. 60 only on interstates, lowers mileage.

Our Rav4 gets no where near reported above.

I'm thinking Alice and her Rav4 do not have ethanol in the gas! also my Rav4 almost always gets 1 mpg less than the car shows. we like to do the math the old way. Nancy
