Welcome to the forum!I don't know anything about that park, but Prospect would not have been on my radar for one. Diamond Lake RV Resort is suited to bigger rigs and nice people too. Sometimes the mosquitoes are friendly too! LolIt's still a drive from Crater Lake though. I don't know of anything close to the park suitable for big rigs like ours.In September there will be a group of us meeting at Casey's RV at Westfir on hwy 58. Maybe you would be interested in joining the group?Kristy
