Gas mileage while towing

[inferno94]

What do you tow, truck spec, what kind of roads, at what speed, and what was your mileage?

Eg.

Seadoo (950lbs on trailer)
'07 B3000 4:10 rear 235/75/15 tires mtx
mainly country roads, ~105kph
13.8L/100km or 17.2mpg
(9.5L/100km or 25mpg when not towing)

6x9 haulmark box trailer, 1,000 pounds empty. (loaded weight varies, never more than 3,000 total. doesnt matter anyways, the tall trailer has wind resistance that acts like a drag parachute. above 45 mph vaccum guage is in the red, below 10", 40-45 mph will run around 10"-12" on vac guage) '93 ranger 4x4 4.0 5 speed with 3.73's on 235/75-15 tires. state routes mostly. truck gets 17-19 not towing and 12-14 when towing this:

Update!

I towed the same load on the same trip today with a reduced speed of 90kph ans much slower starts and managed 10L/100km or 24mpg. Thats close to the best I've gotten from this truck when unloaded!

This is a 180km round trip with three small towns to pass through and a dozen stop signs along the way. That number also includes launching the boat.

I just drove from Chicago to Denver. '92 super cab, 3.0 3.73 rear, 8280 GCW with a full tank of gas and me in the truck. Pulled it ok, and I averaged 15.5-17.5mpg, depending on where on I80 I was. Illinois is pretty flat, Iowa is up/down hills, and Nebraska is pretty flat, but mostly a constant uphill(gradual). Couldn't hold 70 on a hill, but on flat ground, I could do 70.

Oh, and it does take forever to get up to speed.

My truck:
Stock 2002 4.0L 2wd Super cab (160,000 miles)

Fuel economy when not towing:
City 20L/100km (12mpg)
Highway 11L/100km (21mpg)

On a recent trip to the cottage, I towed this:

There was a dirt bike in the back (~200lbs) and probably 400lbs of patio stones.

The trailer was full of mainly books. I have no idea of the weight of the trailer, but I'm sure its close to 3000lbs.
Total weight of everything is 3000 to 4000lbs.
I drove all highway while being very nice to the gas pedal, driving 55mph to 60mph and got 14.5L/100 (16mpg)

I have a 16foot Dovetail car transporter trailer, it weighs 1880lbs empty.

Towing it empty from Wyoming back to Pennsylvania with my 1987 supercab
(1993 4.0, 5sp & 4.10 gears) last September I averaged 18mpg at a steady
70mpg (On cruise control with the A/C running full blast)

I typically get 19mpg "around town" and have gotten a best of 22mpg @65mph)
with the 4.0

In the same truck with a 2.9 engine (same gears and trans)
I'd tyically get 24-26mpg on long highway trips.
Hitched to the trailer (unloaded) my mileage would drop to
around 16mpg, loaded with a 4000lb milling machine in early
december 1999 I managed to drag my mileage down to 11.8mpg
at 65mph

With 4.10 gears I don't seem to get the peak mileage I could
get with the 2.9, but the 4.0 doesn't get "dragged down" the
way the 2.9 does.

I'm about to regear the 4.0 because it's "unhappy" above 70-75mph
with the 4.10's and my 235 tires.

And if you've ever tried to cross Nebraska limited to 65-70mph...
