If diesel is being considered, what is the difference between the Sprinter diesel and the Promaster offering? Similar tech?
Also, again between Sprinter and PM, which is the better RV platform? I know many on here use their vans for work — I intend to convert mine to RV.
Again, any Wiki or such that lists the different PM options? Long vs. short wheelbase, raised roof vs. normal, different engine configs, etc.
Thanks,
The Mercedes engine is smaller (2.1 litres) and more highly turbocharged. The Fiat/Chrysler engine is 3.0 litres. The fuel injection and emission control systems are pretty comparable. The Mercedes uses a torque-converter 7 speed automatic transmission. The ProMaster uses an automated manual transmission, which is different to drive. It doesn't "feel" like a normal automatic. I haven't driven the ProMaster diesel but I have another vehicle with an automated manual transmission that is the subject of much derision in the press (and Car&Driver wasn't kind to the ProMaster's transmission, either). But ... you either get used to it and after that, it's fine ... or your head explodes and you never get used to it. Test-drive.
The number one big difference between these two vehicles is the drivetrain layout, and as a result of that, the ProMaster has a lower loading floor and, if you are using it as an RV, this means a lower step-in height.
The wheelbases (3 different) and lengths (4 different) and heights (low or high) and allowable combinations are best seen by going to Ram's commercial website. I opted for medium wheelbase (136") low roof because it's the biggest one that has a hope of just barely not quite fitting in a normal parking spot. The longer ones, forget it. Low roof because it means less frontal area for less drag and less fuel used, I don't need the extra height, and above all ... it has to fit under a balcony at my house.
If you are building an RV and you want to walk around inside it without ducking your head then you are going to want high roof. The only wheelbase for which high roof is not available is the shortie (118").
The ProMaster has a seating position and steering wheel angle which is unlike that of a car - and unlike that of a Ford Transit or a Sprinter. It's more upright and the steering wheel is sitting flatter - more towards transit-bus than car. That doesn't mean it isn't comfortable but it takes some getting used to (and the seats are very adjustable). I've done a 14 hour drive with only the usual meal and fuel stops. Also be forewarned that if you opt for the divider between the cargo and driver compartments, it restricts the amount that the driver's seat can move by quite a bit.
