Thanks everyone, After I made my post, I also saw the AAA site on this route. Some of the descriptions say there's a very steep descent into Nv. from Kit Carson Pass. Also, is it a steep grade up to the summit as well? We'll be going before the snowfall so that won't be an issue.
Thanks
If you take your time especially going down it is very doable in any RV. Use the gears and if you have a diesel use the exhuast brake. There are other things more important to worry about then getting from Carson Pass to Topaz. After you travel it you will wonder what all the fuss was about.
