I had a RWD one ton van and feel like the promaster is better handling. Not just the FWD, but the lower floor lets me keep the weight lower in the chassis and it feels better even on dry roads.IMO, the FWD of the PM does not improve winter traction. A full camper buildout has nearly equal weight on the front and rear axles. My subjective experience from owing a ford e-series RWD van for 15 years and now the PM is that the FWD PM does not perform better in the snow than the ford did.
I recently traded my Transit for a new Promaster . Wish that I had kept the Transit for a number of reasons . The Ford Eco-boost gets much better gas mileage . The Dodge transmission is constantly shifting , it cant seem to make up it's mind what gear to be in . In the four years I owned the Ford I don't think that I ever heard it shift . The Transit ride is very plush while the Dodge rides like a "TRUCK" . Just my humble personal opinion .I know this is a Ram Promaster forum but without being biased if you had to purchase a cargo van again. Which van would you purchase and why.
