Yeap, Coyote 5.0L and it is much better than I thought it would be. Pulled 5,000lb. load around today and it didn't even seem strained at all. The transmission seems much better than what was in the Silverado, certainly smoother and isn't constantly hunting for a gear.
Absolutely loving this truck. I can't believe I waited so long. I wanted a Tundra but couldn't find exactly what I wanted. I now know the F-150 was the better choice for me anyways.
Wish you all the best at solving this beast. It seems all of the brands have some issues, just got to decide what you can live with. I couldn't live with the shaking any longer.
