Were getting 8MPG @ 65 MPH with only 3000 miles on the driveline. Hopping to improve as engine breaks in.

My last trip I bucked a headwind all day on the first day out. Got 5.2mpg out of that tank. We went 3,200 miles and averaged 8.1 mpg towing our Jeep. I was pretty happy with that!! Used to get 9.2 mpg before we started towing, but it is worth it to have that sense of security and freedom to explore.

Mine is a 315 SE normally pulling a race trailer that is around 7,000 pounds. The normal ground around here is up and down but basically just normal elevation changes. I normally drive with the rig in tow mode and can still get around 10.5 - 11.4 out of it. Get yourself a ScanGauge and USE IT - a lot of information to be had and you can adjust your driving via the gauge to increase your mileage.

Took my 350 out last weekend for it's first trip towing the Wrangler, about 7.5 to 8 MPG at 60 to 70 MPH. If your running your generator expect to burn about 1GPH

Yep, I think I'm OK now. Thanks for all the great data everyone.

Just got a service engine soon light on the last trip though. Says high voltage on both upstream O2 sensors. So now I've got to work that out.

Just returned from a trip from Texas to Westcliffe, Ouray and Telluride, Colorado....approx 1,800 miles RT. 2010 GT 378TS.

I was surprised! If the computerized dash info system is correct, I got 7.1 mpg towing a Jeep Liberty and running the genset the whole time to provide addl A/C. It's HOT in Texas and the lowlands of Colorado this tme of year. A lot of mountains and summits to climb also..... Running at 60-65 mph when possible; pulling Monarch Pass it slowed to 35 mph.
