The majority of interstates have a max of 6% grade but a couple others come to mind:
I-70 west of Denver:
Eisenhower Tunnel area around MP215 at 11,000' elevation has a west downhill of 7% for about 6 miles
Vail Pass on I-70 westbound also has a 7% for 7 miles
Just take your time and it'll soon be over. :)
Highly recommend that you purchase the 'Mountain Directory for Truckers and RVers - West Edition'. It come in East, too. We used it all the time because we enjoy secondary highways and 'most' mountain roads don't bother us. The first biggie is the hardest! Then you'll be a pro.
Do you mind my asking why you prefer to use secondary roads vs. interstates?
The secondary roads offer much more scenery, neat towns to explore and much nicer campgrounds than found along the interstates.
However, we're retired so we don't mind slower travel and we don't put in long driving days - 4 to 6 hours, sometimes less. We rarely made reservations so when we found a place we wanted to explore more, we stopped. We never had problems getting campground sites and we always prefer public parks to RV parks. It worked for us but everyone is different.
If you're still working and have limited vacation time then most folks travel interstates just to get there faster.
