Additional information from Ford I happen to see recently, it appears the new Transit’s maximum GCWR will go up from 13,500 to 15,000 pounds. It’s not clear which engine options will be required for that rating. The presentation mentions that the EcoBoost V6 will be available in Cab and Cutaway chassis for first time, but that doesn’t necessarily mean it’s required for maximum towing in my opinion. It could be the diesel that has highest GCWR. Anyway, the new 15,000-pound rating should make it possible for Transit motorhomes to tow heavier toads (and trailers).
The video also confirms that AWD will be available with Cab and Cutaway chassis options. This info is at end of video.
