Targhee Pass on route 20
Will be camping in Idaho Falls before heading to Yellowstone N.P. How is the drive on route 20 over Targhee Pass into W. Yellowstone? We're pulling a 30' 5er with my 2015 GMC 2500 4X4 (gas).

The above are correct. Ashton hill will be more of a challenge. Targhee Pass is a 3% grade.
I have not been able to find a spec for Ashton hill but I have been over it more than 50 times. It is a very good road that is mostly straight. No sharp turns but I would guess it is about 4-6 % grade.
If I remember right it has a passing lane all the way up from Ashton.
You will climb about 1000 feet in about 5 miles. The problem being a steady climb for 5 miles.
