191 north out of Rock Springs long staight uphigh grade to Farson. Easy because it is s long. Farson to Lander easy. The down hill grade into Lander much steeper. South Pass pretty easy this time of year. Just to be safe while in Rock Springs dial 511 for WY weather. I always check for wind warnings any time of year going over the pass & down to Lander. Coming down into Thermop you'll enjoy the wind river canyon. Those tunnels are high enough. Unless you have reservations a lot of RVers stay at Walmart in Cody. West side of lot.
You may want to fuel up at Flying J in Rock Springs.
That Sleeping Bear RV park in Lander is nice.
