8% is pretty minor in grade. I'd hold direct if a long interstate style road with long curves. With curves the gear below for 35-45 with a diesel. 2 gears below direct in most gassers. I was usually in the gear below to go down the 35 mph 11% grade to the North of my house, same with the 9% going south from my house.
Its when you get on the 15-25% grades on local city and county roads around Seattle etc those usually get me worried. 8% unless there is a hairpin, nothing to worry about. Or try the 6 miles from Timberline to government camps 10% grade with 2" of compact snow and ice, blowing 30 with gusts to 50 mph. That will get your knickers up! Chains on all 4 of the truck, two of four on trailer. No problems.....I even lived to write and tell about it!
Note to self, do not type using smart phone, it is WAY dumber than I.
