Doing some trip planing. The Good Sam Trip planner routed me from Grand Lakes CO onto HyWay 34 on my way to Minnosota in Aug. I have a 38 ft Class A with CAT 300 towing a Honda CR-V on dolly. ...
Thom02099 lives in the area and knows it well. I lived in Estes Park 8 years.
I DO NOT recommend Hwy 34 thru RMNP for RV's of most any size. Even with mountain driving experience. Why? Lots of steep up and down, lots of unguareded dropoffs, lots of switchbacks with some blind, etc. And, trust me, lots of idiot drivers which are bad enough just driving a tv.
