What am I missing in Grand Teton?

Thanks for the question, Mountain Mama, I was going to ask the same thing as we have a Chebby 3500 SRW long bed. And is it much of a shelf road? Have learned I am not as good at cliff hanging with a vehicle as I used to be (maybe I am just smarter!)

I have a post going as well seeking info (Y GT G) as, God willing, we will make the trip again in a year. Have been to them all several times but want one more shot at it.
