Veebyees, you just asked for opinions, which instead of listening, are refuting because your mind’s already made up.....
That aside, the prospective buyers that are going after 15 year old campers, especially ones that have that “lived in” feel, are probably going to be more receptive or appreciative of the-repair parts, tools and dishes etc. So, in general I agree with you.
There’s a big difference between an older RV that was used for summer vacations and seen very little wear n tear and one that has been well used.
