I'd like to know just what kind of miles per gallon you all are getting out of your expedition vehicle? Please put in the model, year, type and maybe even engine size/#cylinders. (I'd love to do a poll, but it would be comparing so many different apples, oranges and fig newtons, it wouldn't be relevant.)
I'll start: I've got a 1989 Toyota van 2WD LE, gasoline, 4 cyl, and I get 21-22mpg in town and 24-5 or so on a long highway trip.
We have been pulling our 13 foot Burro with 2 L diesel‘s since 2003. Our current car is a 2016 BMW wagon. The best we’ve gotten pulling the trailer is a tic over 30 mpg on a 700 mile round-trip with a tailwind both ways. Average is about 27 Mpg. Usually don’t drive above 70. I have cruised at 80 and mileage dropped to 22–23. Without the trailer on the highway the car gets @ 50 mpg. The eight speed transmission really keeps the little diesel in the sweet spot. Towing I put it in sport mode which firms up the suspension and stops it from shifting into 8th gear.
2001 Chinook Concourse XL - E350 V10 DRW, 9,500lbs, only had for short time but on 18 hour drive back averaged 10.5mpg at an average 68mph. Normal driving getting between 10.5 and 11.3, depending on road - (readout from ScanGuage II).
2014 Jeep Grand Cherokee Overland, V6 Pentastar, 140k miles, highway 21mpg, city 18.5 - 19.5 mpg.
I have found that the more I read forum threads on MPG the higher my MPG gets. I'm up to like 40 mpg now. No crap! I get 40 in my Transit pulling 3 military trailers uphill. My V10 I just sold got 45 with a load of bricks in the back on washboard. I just bought a little commuter car, 300 miles per gallon!
I have a high roof extended 2016 Ford Transit and thus far I have put right at 38k miles on it. It has a 3.7 with 4.11 rear end. The best mpg was 22 driving across Missouri & Illinois west to east on US 36. I dove 55 the whole tank.
On on the 3600 mile trip to Colorado/Utah from Indiana, doing 55 on the main secondary roads and whatever on the forest service roads I averaged 19.8 for the trip. I drive with a very light foot. I did not encounter any heavy head winds.
Driving it back & forth to work 8 miles each way I get 17.
It is a very light camper with a galley cabinet, overhead cabinets, Truck fridge 130, 2-105 Ah agms, cassette toilet & a raised bed.
This summer heading into heavy head winds in Kansas at 65 mph I got 15, I also had a Suzuki DR200 mounted on the bumper.
1989 E-150 2wd Sportsmobile Penthouse with just paneling and insulation, no interior fixtures. 4.9L, C6, 3.08 R&P, 225/75-16 tires. I keep it full of construction tools. Typical daily weight is 6-7,000 lbs.
17 mpg highway, 14 city. I drive 65ish on the interstate, just get to the speed she's comfortable and hold the pedal steady mostly. Drops to 60 on most hills and hits 70 or so going down.
Expecting the M5OD swap (with 3.55 R&P) I'm working on to improve mileage a bit (20 mpg hwy is my guess) but mostly doing it for fun and to keep a 30 year old automatic transmission from ruining my day.
