The 275 on a 20" rim is a 34" tire. Ford trucks come with tires as short as 31". Your 295 is a 35" tire on a 20" rim. My 33's do well with a GCW of 19k lbs running 3.73 gears, but I would not want 35's with my stock gearing and current weight unless I was a flatlander.
The 6speed automatics being put into current trucks have really low 1st gears that minimize the need for low rear ends. I'm just seeing a lot of older truck owners giving advice to extremely late model truck owners without understanding that current trucks are simply much more capable in every way than even something from 5 years ago.
Over the last week I drove my truck loaded with the camper and family over more than a couple of Northern New Mexico and Colorado passes over 10,000ft with plenty of power to spare: with 35" tires and a 3.42 rear end. 70mph left me in 6th mostly with occasional drops to 5th gear. Current trucks really are a different animal.
