Come on James - I read the MotorTrend three part review of the 2018 Power Wagon, also. Mileage was indicated - - City- 11+ Highway- 15+ Average- 13+ Not real great but its what you get with a heavy, low geared pickup. Obviously, nobody buys this unit for its sparkling high MPG abilities.
Right now my BIG concern. Which Smart Phones are compatible with the UconnectPhone system on this beast. I've been able to determine that my nine year old Samsung flip phone won't cut it. So I go to the Uconnect site - FINALLY find their list. Kee Rist - this list has phones that are, at least, five year old or older. So an email to Uconnect - asking for an updated list.
Who ever wrote the mega-page section on all the ins/outs of Uconnect, security, Travel, remote start, remote access & all the interactions with Uconnect - missed the boat. H*LL - I'm not even sure his boat was in the water. The good part - with an appropriate smart phone it appears that the entire operation is almost Plug 'N Play. There is also a "help" button for a real live tech who will provide assistance.
