Hey CR,
The 4BT Cummings would be interesting and keep it inline with Dodge fans. Being that its mechanical a swap would be a piece of cake so to speak. I think it weighs close to the 360 V8 but offers much more low end torque. I know the Dana 60 rear end would not have an issue with it. I would just need to find a suitable transmission. Peaking around the net a bit I found several in the 1,700-2,200 price range so not to bad on the wallet either. I think realistic fuel economy with this option would be somewhere around 28-30mpg if the aero was on point and the correct gearing is chosen. Not bad for a 1 ton 12 passenger van. I think my only complaint with the 4BT and this is common is the heavy vibration at idle these engines exhibit. Other than that I could definitely see a 4BT in the Sportsman Van.
