I've owned Dodge trucks since 1974, haven't owned a car yet,, ( wife has her cars), Bought a new 06 diesel, like the ones in the past, only this one has a 4sp automatic and high 3:73 road gears. Pulled a friends 3830, and wasn't happy with the auto trans. We have a very hilly area, short, but steep up and down hills, and this is the first time I wasn't happy with the auto trans,, Ordered another 3500 with 6.7 and a 6 sp auto.. I've been monitoring several Dodge truck web sites and all so far are very happy with the new 6spd. Well, we'll see about the last week of this month when the new one is suppose to be here,. For myself, I have a Kubota L48 and use a BRi-Mar 12000 trailer, My machine is 8200 and the trailer is 3100, a lot heavier than that 3830.. Being one that owned and operated tractor trailers many years, ran town highway dumps and other people's various size trucks, I feel very knowledgable on class 1 -5's.. Class 8's have changed a lot since I owned the last one and have no reason to keep up on those today,.. Goes to show you what we think will work and last a long time, isn't always the way it works out.,..
