Luther pass, aka South/North Truckee Rd, was extremely crowded. I would suggest arriving early to get a decent spot. We ended up going onto North Truckee Rd and found a pull off wide enough for our truck and rooftop tent.

South Truckee Rd did have toilets about the halfway point of the approximately 2-3 mile long loop. Be mindful that this some spots are right next to a busy Highway.

Overall, would return again and arrive at an earlier time.
