Any T680 Owners? Would love some feedback.

this truck was designed on computers, and shaped in a wind tunnel, and they can't keep the side windows clear...... eye vay!

 

That's a good point - tech is great but real world is important. Maybe they should have added some dirty water to the wind tunnel.

 

Nobody can. Thats true. I repeated it 1000 times and will repeat again: nobody drive what they trying to design. Its a shame that women with 3 grade elementary school education trying to design truck sleeper interior, etc.

Only blatant clueless "engineers" unable to design "one hand" operating sleeper window.

 

Just flipped 80,000 on my 2014 model. Still only getting 5.2 - 5.8 if I want to do 57mph on flats I can get 7.2 grossing 78,000 but in PA, WV, NC, SC, OH I only get 6mpg if I go slow.

So average for me is 5.5 - 5.8 averaging 65-72mph

 

US99 in CA. 10plts, all I could squeeze is 10.3mpg for now.

 

You rock.

 

thats some BS man. For an average of that I'll take a 379 or W9..paccar motor blows so far. Already had fault codes at 18k miles

 

Yay, trip average is more decent though - 6.8mpg.

Okay, this is my latest trip average from Windsor On to Belvidere IL. March 19-20, 35-37 Fahrenheit, W-NW wind 15mph with 30mph wind gusting. Mainly flat highway with a little city traffic, two pic ups, two cold starts. 40,200lbs in the box one way, 26,000lbs return. My cruising speed is 59-60mph.

 

I cant see nothing,someting wrong with the app
