Didn't you check it out before you bought it? I would definately buy a new mattress although we didn't and I love the one that's in there. We joke around about it every now and then because we know the people we bought it from but they're expensive. We took our futon cushion and used it for a mattress on the wider bed on the bottom bunk. Some times people just sell things cheap and don't worry about the mess if they're giving a good deal already. Don't know if that happened with you or not. Have fun in your camper. We've had wonderful times in ours and there's no place I'd rather go than up north in my camper!
