What is your MPG/Speed?

[pickerdd]

On my recent 2000 mile trip to Winfield, KS (from Atlanta, GA) I got 12 mpg when I towed my '71 23' Safari with my 2008 V8 4WD Runner. I kept it between 60-65 mpg.

As an aside - I-40 SUCKS in Arkansas and Oklahoma!

I have an 2008 Silverado, 2 wheel drive, with the 6.0 Liter engine. I frequently travel from North Carolina to Northern Indiana and have always watched my mileage on that trip. As a disclaimer, I do use the GM Driver Information Center but usually do a reset when leaving home in order to give me a more accurate data base and have never had any reason to question the accuracy. On my old Airstream, a 1976 21' single axle Sovereign, I usually logged about 11.7 mpg for the trip, traveling at reasonable speeds of 60 to 65 mph. Last month I bought a 1990 29' Excella and was surprised to see that my mileage only dropped to 11.4 mpg on this same trip. Additionally, the new trailer handled and felt much better behind me which was totally unexpected. I now suspect that the dual axles and more balanced hitch weight contributed to the better ride. I also suspect that most of the mpg figures relate to the hole I am punching in the air rather than the weight of the vehicle I am dragging behind me. I also see much better mileage when heading south into Florida on decent interstates with no hills.

wow, i am really surprised at these figures.

On our month long road trip in sept, we started out towing our 19ft 62 gobetrotter with a '84 6.2l diesel suburban, averaging 10mpg from PA to idaho. the suburban died in boise, and we picked up with a 2005 4.7l V8 jeep cherokee, also averaging about 10mpg from boise to CA and through the southwest, southeast and back to PA. it occasionally went down to 9mpg in the mountains and up to 11mpg.

i was actually thinking of selling it in favor of something with better towing MPG.... but after reading this thread, i don't think its worth it to gain what could be a max of 14mpg with a much more expensive, bigger vehicle. I guess we'll keep it

i was nervous getting the cherokee

If the MPG calculations are incorrect then is the odomoter also incorrect because it is also calcuated by the same computer?

Well you ask. 27ft Overlander ,7.3 V8 PS crew cab 2 adults 2 dogs full tanks of Propane and Water, and lots of other junk,15 mpg average at max 62 to 65 mph. and lots of traffic lights cause my wife HATES Interstates. When not towing 12 to 14 around town and 20 highway.

I tow our 24' Trade Wind with a Jeep Grand Cherokee Overland 3.0L Diesel. We averaged 17.2 mpg on our last 14,000 mile coast to coast (and back) trip. I drive 60 mph +/- 5 mph.

I can climb any mountain...provided there is a gas station on the other side.

I like to revise my original post here.

I tow at different speeds but I mostly get about 11 mpg. Thats in the mountains and hills around where we live. I haven't towed on the flat to find out but i'm guessing it would be 12-14 mpg.

We we came down to Zion I towed about 70-75 mph Up and down the mountains. on the flat I hit 80 a few times but mostly drove about 75mph. When we got here I got 9.5 mpg on average. But we did some steep long climbs that I was doing 65+ mph up. so I was only getting about 3.5-5.5 mpg doing that.

Sometimes I sacrifice speed for time. With four kids sometimes going slower is just not worth the wining.

On my last long trip of about 3000 miles, with my 1996 F250 PowerStroke 7.3 I averaged 14.7 mpg, hand calculated. This included some mountain, but mostly flat highways. I aim for 60 mph while on the Interstates.

Like the OP, I've recorded in the 17s and 18s, but it had to be under highly favorable conditions, like tail winds.

[ZoominC6]

We never tow over the trailer tire rating of 65mph unless to pass, especially in hot Summer weather....
12-13mpg with Duramax Diesel towing a 30' Classic with Slide Out....as calculated on the Chevy "Happy Guage" on the D.I.C.
I need to hand calculate this one day.
