I'm purchasing a new F-150 with the Ecoboost engine and I will be using this vehicle for work. I will be towing trailers and RVs across North America for long distances at a time. The only thing I don't know when it comes to vehicles is rear axle ratio and what it means. There are a variety of options I can pick from and I need help on figuring out which is the best option for the kind of truck I will be using. If you could explain why that decision is best it will help educate me as well. Thank you!
