Congrats on the GT and welcome!
I've got both, but drive the GT as the daily driver. 10mi daily round trip is tough on diesels, so I let the GF drive the beast the 56mi daily round trip she does (she likes driving the truck over the car anyways). I honestly prefer my go-cart to the truck most of the time. More nimble to sneak through gaps in traffic. Mileage is about the same for both of us, oddly enough. Fuel efficiency doesn't do well 35-45mph stop-and-go.
