I was just reading two articles this week, one regarding the GM platform and the other on the Ram.... was a little disappointed not to see the blue oval out front on this, but just got my Eco last month, so I wouldnt be buying anyway.

One article speculated $6000 premium for the GM which will be converted ex-factory at a dedicated facility, while the Ram is factory inline. GM offering commercial AND retail, while Ram is fleet buyers only.

Ram 370-ish mile range with 8 gallon petrol tank. GM was 400-ish miles with no reference to petrol tank... apparently petrol is needed to start the motor and bring to "temp", when CNG will kick-in.

Got my eye open on multiple fuel type filling station for a piece of property I own, as there are only 16 CNG fueling stations in Michigan, so if this kinda thing takes off in popularity (starting even with Fleet use), infrastructure development along the lines of distribution and dispensing could be a new boon.

Anyway...
