Depending on what condition it is in thats a pretty good price,but this is a buyers market make them give till it hurt, hell offer them 15,000 for it see if they take it or not you can always offer more also welcome to the forum
Where do you live? The further North the better chance you have of talking them down. I guarantee a used car dealer got the unit cheap and they don't want to sit on it for the winter.
I agree with the above post. That is a pretty good price on a very nice camper, make sure it's in good shape,no soft spots in roof,walls and floor. Make an offer and go from there.
