It's an easier pass than most others across the Continental Divide. Steeper and more hairpins on the west side than on the east, so you need to slow down at the top and use your exhaust brake, and not your hydraulic brakes, on the downhill. Some of the hairpins have a 15-25 MPH speed limit and that's for cars, not RVs. If you don't have an exhaust brake, put it in a lower gear at the top of the pass and leave it there until you get to the straight part of the highway along the Blue River.
