Ford's recommendation is to always pull out of O/D. I tend to recommend pulling in whichever gear is going to let you pull comfortably without excessive EGTs or Trans temps. When pulling modest to heavy grades, it is still recommended to downshift or drop O/D as this provides a 1:1 through the transmission. This is less stressful on the transmission components and provide good pulling power to get through the grades.
Yes, driving without O/D will absolutely have an impact on your fuel economy, so use O/D when you can.
