Best and now the 'only' place I advertise my RV stuff or buy RV items is the very well known Escapees Full Time RV Club.
Seasoned RV'ers who know what they want and actually know about the RV stuff for sale! :C
Beats the hell out of advertising on craigs etc where all you get is lookie loo's and scams.
I advertised my tow car and within one day had a ton of calls and sold it for what I was asking forthe next day.
