So one has to "baby" a Promaster in hopes that it will hold up, in other words? I'll take the reliability and dependability of my Ford Econoline "slopbox" anyday knowing that it will take anything thrown at it...lol. and yes, those $40 diy synthetic oil changes are great!First generation Pentastar 3.6's were prone to head problems due to poor lubrication.
They fixed that in 2014 I think it was. Also many of the drivers that migrated to the Promaster came from driving the regular Ford and
Chevy cargo vans and were pounding on them the same way they used to beat on the old vans and found out fast that they couldn't treat them the same way. Once the drivers/owners figured that out, they stopped destroying the cv axles and other suspension components.
Their transmissions are holding up well for the most part.
I don't have overall cost comparsion charts between the long and talls but if you can tolerate the sacrifice of a proper bunk area, my gut feeling tells me that provided you keep up on the maintenance (love those cheap diy oil changes), and don't beat on them like we did with the old slop boxes, I believe the Promaster will end up providing the lowest overall cost of ownership.
