Recreational vehicle

My husband’s sister owns an RV and they usually take it to the mountains or whenever they feel like camping in the desert. I wonder how much it would cost them for rv towing in case their rv (recreational vehicle) breaks down while they were driving in the freeway or somewhere. It must have been costly. My husband is telling me that he wants to have an RV someday; I guess it will just remain a dream for him because we know that we can’t afford to get one. My sister-in-law says that the membership costs 10 thousand dollars. That’s a crazy amount of money for us.
