The short answer is no......but I suppose it depends a bit on gearing.......
FWIW, I've got a 4WD 5.4L, 285/70-17's (33's?), and 3.73 gearing.......
It regularly shifts out of O/D on mountain passes/climbs but gets about 13 mpg.....
and depending on your speed starting an incline your speed at the top may be less than you hoped for.......if you can get up to about 70-75 mph at the beginning.......
