Travel advice on I-70 & I-15

[Navl AV8R]

Will be traveling I-70 and I-15 from Topeka, KS to St. George, UT this fall (September) and am looking for advice/recommendations about mountain travel on these interstates (grades, conditions, etc).

I have a 36' W22 gasser MH and have not taken it into the Rockies before. And of course, I have those wonderful brakes to help? get down the mountains.

Both good roads. Steep on I-70 going up from Denver but you just take your time. the rest not bad. Have taken my 36 foot MH accross this route a few times. Just drop to lower gear coming down the west side of the Rockys. Nice drive. I-15 is not bad at all, no real steep grades.

There are three steep downgrades on I-70 in Colorado :near Evergreen, descent from Eisenhauer tunnel, and descent from Vail Pass. Get your speed under control at the crest ... descend in the same gear that you used to climb the ascent ...

When you need to apply your brakes do it in strong bursts ... DO NOT RIDE YOUR BRAKES ...

There is some great scenery on this route ...

There are two great national parks near St. George: Zion and Bryce
