I am also done with turbos for a pull vehicle. I had the V6 turbo eco boost and it pulled well. But the gas milage pulling was not great. Was told this is the same for all the turbo motors. Good milage empty and you get a 1/3 pulling. Might not be a bad idea to test drive the trucks with your boat and see for yourself what you get. Empty, the turbo was more fun to drive.
Please let us know how they do milage wise pulling. I would be interested to know your results.
I also hate turbos, just one more thing to fail.
The turbo went out on my eco and was quoted $5K to fix it. I am wonder how the blue book is affected when these get up on the miles.
