Kootenai County Idaho Highway 97 – Bad Roads for RVs is located between Coeur d’Alene and Harrison along the east side of Lake Coeur d’Alene. The road along the east side of Lake Coeur d’Alene is narrow and while following the lake edge winds the for 25 miles — non-stop.
Assuming your destination is anywhere near Harrison you should instead use Interstate 90 followed by Idaho Highway 3 which although a longer route is probably faster than Idaho Highway 97 along the lake edge.
We traveled on Idaho Highway 97 on our way to Bell Bay Campground in August 2020.

Kootenai County, Idaho Highway 97 – Bad Roads for RVs — Our experience
We traveled Idaho Highway 97 southbound in our 40-foot RV towing our car, which fit the description of a single axle of less than 48 feet and we regret it. On our return trip back to Coeur d’Alene, we took Idaho Highway 3 to Interstate 90.
We traveled the entire length at about 25 miles per hour.
