What's your fuel mileage when towing???

[lowlife]

My new trailer is about to come in... 2-3 weeks away... I'm planning a trip from BC to Portland... approx 300-350 miles each way.

I'm spliting fuel costs based on how many people are coming with me and I'm towing a 16' enclosed trailer that weights approx 5-5500lbs when loaded and I will have myself and up to 4 extra passengers.

What I need to know is what kind of fuel mileage I can expect out of my 07 Suburban when I tow this kind of weight. I don't really care what it costs to make the trip I just need to be able to tell the other guys roughly what it will cost them so they know what to expect.

Any info or personal experiences would help a lot.

I average about 11 mpg when towing my quads. My trailer is only 6.5 x 10 feet. Average speed about 80 mph.

I'd expect about 10 mpg if you maintain 70mph. Get some trailer brakes if your towing all that weight.

Thanks.. ya trailer brakes and weight distributing hitch are already there...

I get about 11 mpg towing my 2 snowmobiles in a covered trailer and the trailer with both sleds is under 2000 lbs. thats still better than my old dodge that got only 7.

I also got around 11MPG in my Denali when towing an enclosed 2500lb cargo trailer, with 8 people and a dog...at 80-85MPH!

Hmmm... I was hoping it would be somewhat better than that... but then I knew it wasn't going to be great...

It's not going to be great. Depending on the day I get 9-11mpg towing a 24' pontoon that with the trailer weighs slightly over 4,000. I get around 9-10mpg towing a different 6,000lb boat/trailer. It is more aerodynamic than the pontoon and tows much better. Either way it isn't going to be great. Thats towing no faster than 65mph. More speed = more fuel. Especially when towing.

I have a Tahoe with the 4.8 liter engine. Towing about 4000 pounds worth of stuff in an enclosed trailor, I still get about 15.

Never towed with the LTZ.
However when I was pulling my 28' enclosed race car trailer with an '04 2500 Burbon and a 6.0 /3.73's I was getting 10-11 mpg. Weight was around 8500-9000 lbs. No passengers, only me. I realize we're talking apples and oranges here, but maybe it will give you an idea...:yesnod:

The only car I ever tow with is my 2004 Tahoe (3.43, 2WD, 5.3). When I tow the jetskis I drop 2-3 miles a gallon going 75MPH and when I tow the 6200lb boat trailer I usually drop about 6 miles a gallon (coming to about 12-13 MPG).

wow, what a difference in milage the gear ratio makes, on my 2000k mile round trip i averages 14.9 doing 80 with strong headwinds and just me.

when i tow my boat (about 5000 pounds) with six people and coolers i get about 11 doing 70mph and going up and down grades ( i go to 3 and its perfect)

jetskis i tow locally and they get me to about 13.5 with me and a bud since i only have two.

when i tow my atv's which im not really sure about the weight i see no change in milage or pick up for that matter. you dont notice loads unless their super heavy.

Yeah, theres even a difference between the 3.43 and 3.73's. The old Z71 was a 3.73 and we were usually getting about 16.5-17MPG with just the two of us going 70-75 on the interstate. With the 3.43 I have seen it get over 20.5 MPG going 65.
