Towing MPG... Good Lord!! LOL

Guys,

Finally purchased my trailer. Lark 7x16 V-nose with tandem axles and power brakes.

Drove her 50 miles home from the dealer.

Averaged 10.5 MPG over hilly terrain. EMPTY!!!!! I also learned that cruise control is SILLY when towing.

2013 GC V6 2 2WD

The fuel to get me the 2000 miles back to AZ is gonna cost more than the trailer, LOL

V8 right? Something may be dragging? I routinely get 15mpg on a 6x14 flat front loaded to the brim and ~65mph hilly interstate.

Perhaps use tow/haul, if you have that button, with the cruise control. Works smooth for me.

What kind of mileage are you getting without a trailer?

No sir, sorry. Should've stated: 2013 GC V6 2WD.

Avg day to day typical use ~20MPG, driving like an ***.

Even with that v-nose, you will still get a lot of wind-resistance that's going to knock down your mileage pretty quickly. Nature of the beast...

Almost every SUV for pick up I have owned has returned worse MPG with v6 vs v8 in regards to towing. That's why I always get the larger engine except in the case of my XJ.

He's an angel dressed in oilskins; he's a saint in the "Sou'wester,"
He's a pluck as they come, or ever can;
He's a hero born and bred, but it hasn't swelled his head,
For he's just the U.S. Government's hired man.

Aside from this one trip, I will probably never tow again. The V6 is just fine day to day. I was just shocked at how dramatic the MPG change was!

Hope that the wind is at your back during the haul. It helps on fuel efficiency...and hurts it if it is in your face.

Maybe you can stack that deck with route planning?

To be fair that trailer empty probably weighs in around 2700 pounds or so empty, and that's not taking wind resistance into account, so your already over halfway to your towing limit.

That's a pretty big trailer to put behind the V6. Especially an enclosed trailer. But 10.5? Dang is that low! Wind resistance it a b!tch, lol.

I am lucky to get 11 towing my 6x12 v-nose trailer with a Hemi, so this is not surprising. Even the v8 struggles with the wind load, I tow double the weight with an open trailer+car, and it is much less stressfull and mileage in the 12-13 range.

I get 17 - 20 mpg towing a 8x16 trailer with Miata, 2 sets of racetires on a rack (has some big wind resistance) and other gear loaded inside my WK. As I have to tow frequently I bought a CRD specifically for the huge fuel savings when towing.

take off alittle slower and dont try to out run everyone. do the speed limit on the highway no need for 70+ mph.

also check you ball for its max capacity. had a friend recently buy a 2in ball that was rated at 3500lbs. i had him throw it away, well no he put it on his atv. and bout one rated for 7500lbs.
i usually tow a 6x16 open deck, but dont expect to get above 13 mpg.

I don't know about you but 70 is the speed limit here, and most of the time going 70 you are still getting run off the road and passed like you are standing still.

I just did the same thing as the OP (purchased a new to me travel trailer) and I was also as others have said averaging 15 mpg after driving home 120 miles....i also have the Hemi V8 tho.....and was driving thru some very large grades thru the mountains on the way home.....i used cruise most of the way and left it in tow/haul mode, so not sure why you said towing with cruise on was a joke....stayed and 60 where I set it for me.

It's also 70 mph mainly where I live and I go faster when I'm in a car but when I'm towing I go 60-65 mph and simply set the cruise. When you almost double the weight of your vehicle it's not the smartest thing to have to drive as fast as everyone else. Just stay out of the way - time your passing (if you have to carefully) and keep an eye on your mirrors. Your mpg is much better, you don't abuse the trailer and tow vehicle as much trying to drive it like the trailer wasn't attached.
