Etiquette on contacting past owner of your new RV

I am not as self-centered as some, so please feel free to contact me about my former RV. I would be more than willing to be helpful to a polite, courteous, and respectful potential RVer. I am happy to answer your questions, but show me disrespect, ignorance, and or become argumentative and all you will hear from my end of the line is silence. IMHO being kind and decent to others is only common sense which usually pays positive dividends.
