We have a group of 7 in a 31 ft long RV and another group of 12 in a 24 ft toyhauler what do you recommend

Check out Kaibab RV park. Very nice people and super friendly. You are just outside the park. Is about a 50 minute drive to the north rim.

When the NR opens after the Mangum Fire, reference this link: https://www.nps.gov/grca/planyourvisit/cg-nr.htm Make your decision from the facts presented here. The North Rim Campground is AMAZING!
