Then, honestly, that is probably what you can expect as well unless you slow down to 65 then you will probably get a bit closer to 10.Thanks. I live in Tennessee so there is no such thing as a flat road. All my buddies that we camp with have dodges and they get between 6 and 8 at 70mph.
...We just got back from a round trip starting in Ellis County in North Texas to Port Aransas Texas.We put about 900 miles on the truck pulling a 6000 lb + travel trailer.I was pulling at 62-70 mph coming and going and my mpg was in the 8.5-9.1 range and this was hand calculated.The truck only had a little over 700 miles when we started out.I am not complaining at all about the mileage,but do wonder how others get over 11 mpg on their setups that weigh more than what I have.This was my first time pulling with the 5.7 motor and it really seemed like 70 mph was a good easy speed to run.The area we were driving thru is by no means flat and I know that will play a part in the mpg.The truck is a 2013 crewmax LTD 4x4 and it did replace a 2010 dc 4x4 with the 4.6 motor ....NOT TAKING AWAY FROM THE 4.6 BUT THERE WAS A BIG DIFFERENCE DRIVING THRU THE HILL COUTRY WITH THE 5.7!!!! I am thinking with more miles put on truck that my mpg will possibly improve.Looking to upgrade camper and that means upgrading truck also. Was wondering what kind of gas mileage a 5.7 crewmax would get with about a 6000 pound load.
Never really checked mpg with the 4.6,it was thirsty I know for sure.The 5.7 is just a lot better towing the 6k travel trailer.It tends to stay for the most part in 5th gear with an occasional drop to 4th.The 4.6 was wandering between gears alot unless we were on level ground.And yes a/c was on for sure and there were not alot of flat roads until we got to the coast.Not concerned about the milage just wondering about how to get a little more out of it without dropping to 55 mph.Brand new and with the a/c on, makes sense, should improve a bit with time. What did the 4.6 pull with that trailer, 2013LTD?
Just wanted to note, the worst handling you'll probably ever experience with your TT is the trip home. The weight in the trailer is really not distributed to be driven empty. I'm betting that loaded up for your first camping trip it'll tow even better.On a side note, I wouldn't want to tow anything much heavier than this trailer once we get it loaded. A few times on the way home I was thinking about people on here stating that they're towing up around, or even over, 10k lbs, and I was just shaking my head. This was with a 4-point Equalizer WD hitch with no sway and no bounce.
