Tow mileage abysmal

I’ve towed our TTs all over the place on the highways and interstates in the right lane and never more than 60-65mph. Haven’t died yet.

 

But do you… almost… die? Inquiring minds need to know.

 

Every. Single. Day.

 

Story of my life.

 

Hows it feel to be hated? Lol

 

Well honestly it…. Who am I kidding. I couldn’t give one flying shit about what anyone on the road with me thinks. I’m safely operating my vehicle. Driving 70+ mph towing heavy is just asking for a situation that will be beyond the vehicles ability. Go around.

 

“Go around”

thats the spirit!

Just got back from a trip out west towing a 6000lb travel trailer behind my 3.0 Duramax. Wisconsin to Colorado. 2000 miles there and back. Averaged 13.0 mpg running between 67-73mph depending on road conditions, traffic, and terrain. AC on the whole time in 85+ heat. Averaged 28 mpg for 700 miles unhooked the entire week we were there being a tourist.
My next truck (retirement rig) will either be a 3.0, a big diesel, or a tundra. Prob depends on the size of the camper!

 

That’s some mighty fine Mileage. I’m a bit jealous.

 

DEF consumption went up from about 1300 mpg for regular driving to about 200 mpg towing. That added $50 to my fuel bill.

 

I found the same thing with my DEF consumption. During the last trip, our I had to add a couple of jugs of DEF. We were carrying about 5,000 lbs and still got 14.5 mpg but the DEF usage sort of evened the playing field compared to gas.

 

Can't beat a diesel for towing. Period. Mileage, power, ease, there's no comparison to gas at all.

 

Pulled this back 100 miles through ATL traffic and averaged 17 mpg.

 

2025 sr5 4x4 I average 11.9 mpg pulling my coachman apex nano 185bh camper . The camper is fully loaded and 3 mountain bikes a small generator and a weeks worth of food and clothing . I say it about 4000 lb .

 

The camper is bout 3200 lb empty

 

Goal: get there, not get there fast or not at all.

 

I just towed this from Colorado to Montana and back. Much of route has 80 mph speed limits, which I love. If I didn't periodically check the rear view mirror, I wouldn't have know the boat was back there.

Overall, I got around 15 mpg. I'm fine with that.
