Getting across western PA

Looking for some experience / advice.
Planning a trip in June where we will be heading for Minneapolis area from home close to the Maryland / PA line close to Gettysburg PA.
I have been out / up RT70 through Pittsburgh a few times and not looking forward to 70 / 76 through the hills and the Pittsburgh area itself, but it's been 10 years since I last did it, so my memory may be exaggerating the "bad" of that leg of the trip.

I was considering running up to Harrisburg and out 322 / 22 and then onto 80. It's only and extra few miles and I go to the State College area occasionally and didn't think the hills that way bugged me quite as much, even recently dragging 7K Lbs of TT behind me, but never been out across 80 past that area.
So I guess the real question is if 80 is smooth sailing enough to be worth going that way?
Oh, and we might leave the first evening and do this section in the dusk to dark and park for a nap somewhere close to the PA / OH line.
Thoughts?

we have been that way numerous times.....and your plan to get to the Oh/Pa line is good...but leave a little earlier,so that you get to the first rest area on 80..Ohio Tpke.....that rest area has a RV designated section with elect hookups for $20. also water and a dump station....and safe...Chuck
