I've read a lot about the fuel milage and good and bad about the Dodge Pro Master. But I'm just wondering what the drivers are feeling about the power that this 3.6 engine puts out. How do they feel when empty, how do they feel when loaded to their max capacity? Do they easily run 70+ mph when loaded? How well do they handle the larger hills? Just curious because I'm looking at a Transit and I have a choice of the 3.7 Ford engine with similar power ratings or will I need to step up to the 3.5 twin turbo Eco Boost engine!
