Within the next year or so I’d like to sell my truck for another used F150. While the 3.7 is a great engine and Ive had no issues, its just not the engine for a crew cab F150. 55 mph and under, it gets great mpg, anything over that and it really starts to show that the truck is under powered. Im considering either a 5.0 or 3.5 Ecoboost. If I were to go the 5.0 route, should I buy a 2017 or older truck due to all the oil burning issues? Also the truck I want may be very hard to find, it must be 4wd and have a 6.5 foot bed. I just cant stand having a 5.5 foot bed anymore, its useless. The large 36 gallon tank would also be a plus.
