Yup, I am quite interested in the Dynamax Rev TB as well. Lots of features for the money. I, too, wonder about the single rear wheels. For me the MB Sprinter chassis and diesel are the benchmarks. I would consider the Ford E350 or E450, but I like many aspects of the Ram Pro Master 3500 chassis and engine. Not much available yet to see in terms of Dynamax Rev TB videos, etc. Looking forward to hearing and reading more about the Rev TB. I don't plan to tow, so I am not concerned about its tow rating. Interested in its MPG, though.
