It might be interesting to a few of you to see the view from the drivers seat.
The steering wheel has the usual functions of volume, phone answering and cruise functions including the intelligent cruise features to keep the distance the same to the vehicle in front.
Left stalk is the indicator and wipers and the right is the engine brake and gearbox modes. The gearbox has 3 modes with auto ECO, auto ECO off and manual. For normal driving you stay in eco mode for economy but when pulling away heavy or smaller roads or hill/mountains you may want to turn the ECO mode off as the engine will rev more between changes and give you more momentum. Manual is useful for lots of conditions and I like to use it just bore a hill where you can drop down a gear or two to get the revs up so when you start climbing the truck is in the torque band early. As soon as you are climbing and pulling hard I put her back into non ECO and the electronics do the rest.
The engine break has 3 modes with 1 being very gently slowing to 3 where you can get to a stop without touching the foot brake. Ideally, you use all 3 settings instead of the footbrake to keep you moving faster and more economically. You'll often hear a different engine note when a truck is slowing and this is the engine brake working.
Not all trucks have the 3 gearbox modes and are set in ECO and boy oh boy are they slow!!
The other pic is the rest of the cab with the usual array of for hill hold, hand brake, gear selector, diff lock, lights, air con, sat nav radio etc etc.
I've also attached a couple of pics of what I cab see from the drivers seat.
