INPUT WANTED ON KW T660/680
I would like to have some input from anyone who has or is currently driving a Kenworth T660. I am looking into getting another OTR truck and this is the model we are looking at now. It's a 2009 with 400k miles, Cummins ISX 15 with 485 hp, 1850 torque, 3.55, Eaton 13 speed, 72" bunk with APU. We currently have a W9 and it's a great truck for pulling hoppers, but the mpg isn't the best, but the scale weight is only 17,500#. We will be keeping the W9 as we look for another OTR truck. The ride in our W9 is very smooth, so if we were to replace it, the next truck needs to be just as good.
Some of the features I like about the T660 is that it is lighter than the W9, more aerodynamic, and on paper should get better mpg, but at the same time have the durability of a Kenworth truck.
I would like to hear about others experiences with mpg, the ride of the truck on rough interstate roads, sleeper comfort and quietness during the night. The APU should help, but if the truck has to run at night, how quiet is the sleeper? Also, if anyone is driving a T680, I would like to hear about that as well.
Thanks,
Ryan
