What about the true Medium Duty AISIN?

You mean the one used in the Nissan Titan...

I think the comments about "medium duty" engine and tranny really aren't valid arguments, especially when the person who makes them can't seem to explain why that makes them better. I also know that the Aisin A466ND used in the Nissan isn't the same as the AS69RC that is in the RAM.
:S

Speaking of Aisin, we just had two in our mobile service truck 5500s replaced at one of our Ohio dealerships. Failed line pressure solenoid from what my corporate fleet manager said.

If I am not mistaken, the 6.4L used a Siemens K16 VDO HPFP, not a CP4.

I can reply to this with a little different perspective. For a living I am a self employed mechanical inspector. If it has wheels and drives I’ve probably done a mechanical inspection on it. I’m hired by insurance companies, extended warranty companies, manufacturers, lawyers, and others. From my experience both are good engines. However of the 3 main light duty truck Diesel engines (ford 6.7, Cummins 6.7, duramax 6.6). The duramax is the least dependable. All generations of the duramax 6.6 suffer head bolt stretching that leads to head gasket failure. This is especially true in cold climates. Head studs seem to take care of the problem but that’s after 20 hrs of work and $2500 in parts. The cummins seem to have the least trouble of all 3. And since the earlier cp4 pump disaster in 6.4 fords. It has tuned out to be a pretty reliable pump. The Alison tranny is better than the 68RFE however if both engines are left with stock power levels the 68 has been a strong transmission too.

Maybe. Maybe not. I haven’t seen a lot of love for that new design from anyone - be it automotive press or owners forums.

The looks on the Chevy are …..causing some discussion, the looks on the GMC are getting very good reviews. The interiors are functional and clean but not the level of bling you see in the top shelf Ram. What will save the Chevy is the performance. With what appears segment leading tow ratings, limited nanny input and a lot of tow technology, it wont be hard for a serious buyer who uses an HD as an HD to jump to the 2020. There will be those that like the '19 styling and are not tempted by what the 2020 brings to the table. However I don't see GM struggling to sell the 2020. If they hadn't stepped up their HD game, I would agree.

The leftover 2018 ram diesels here are selling for 20k off before negotiations. And with the strong US dollar, I’m surprised more people aren’t coming up here to buy them.

In order for an American to buy a truck up here in Canada he would have to buy slightly used. An American can buy one used vehicle per year and import it into the USA very easily if he drives it across the border himself (there is a little bit of paper work that has to reach the border 3 days prior to the vehicle..... a recall clearance letter). Warranty can be an issue. Ford warranty transfers. GM warranty transfers but there is a period of time it is interrupted for (I think maybe 3 months but I don't remember). Ram warranty does not transfer.
