I don't want NA gas since I tow at altitude often.

? It's the turbo that helps at altitude, not gas or diesel.
EDIT: sorry, didn't catch the NA = Normally aspirated (was thinking North American for some reason)
All the Ford Ecoboost line of gas engines have turbos and work well at altitude.
The 3.5L EcoB that's available in HD Payload trucks does not have the low rpm torque that the 5L Cummins has, nor does it have an effective engine brake. But otherwise is a competent performer in the "Heavy-half" country. Probably a lot cheaper too, but for that we'll have to wait and see.
