None of the public campgrounds will allow 2 months stay. However, you can make multiple reservations to cover your 2 months.
Contact line pine store for more information
Contact the hiking store in Lone Pine. I can't remember the name but they should be able to help you. I'll be there in 2 weeks, I'll ask around.
Is there any storage places that we can leave our truck and camper for two months while hiking from LonePine to Belden on the Pct?
