My older neighbor lady years ago use to set out a bowl of White Vinegar on her countertops for household odors. She was a smoker and you would never know it.
The vinegar is suppose to absorb the odors in the house. As I say, it's just a suggestion, but I find myself doing it as well.
As for the perfume smell, I too would have said the previous owner may have used Carpet Fresh. We have used it before on our carpets and it is very perfumy. Give the White Vinegar a try. Fill a big bowl, close up your camper for a couple days and see how this works. If it helps lessen the odor, it's a cheap solution. Good luck!
