Well it's not my first time but it is with the Eco-diesel. Was only about 30+ miles and all in the mountains around Knoxville Tn with some very step twisty grades. The travel trailer was a 25' weighing in at just over 5800#. I have towed my boat without any issues at all and it weighs in at 6800# so I was not worried about towing the TT.
The truck felt planted and very stable, the factory brake controller work great, and the trans kept the truck in the torque band at all times. I personal would not tow over the rated specs but have to say from how it handled this trailer, 8000#+ would not be any problem for the truck. The engine brake worked great also and even worked empty when we were sight seeing in the Smokey Mountains National Forest! Thanks GDE this is a must have for anyone towing and even if you don't tow!
Over all this is one great tow vehicle no mater what the Blue Oval boys think!
๐Here is a pic of the truck and TT after I got it over to my BIL house.
