We just did a loop from Denver through NM to AZ, CA, NV, UT and back. I-25 was generally good all the way south with Raton Pass being a very small grade. Once back onto I-70 from Utah, the road condition is pretty terrible for much of the ride through the mountains. It is astonishing how bad CO has let that road get. Large holes, ruts in the left lane, etc. If you’re continuing East, it was terrible for the last 100 miles into Kansas. So, my recommendation is to avoid I-70 if possible unless you really, really want to visit Denver, which is a great place.
