Mantelli Trailer Sales, Inc. was founded by Albert and Shirley Mantelli in 1965. It is currently owned and operated by their daughter and son-in-law, Kim & Mark Watson. The dealership is located in Lockport, New York which is in the western region of the state, near Buffalo and Niagara Falls. Throughout the years, Mantelli's has expanded in size and now would be consider a mid-size RV dealership. Over those years, Mantelli's has sold every type of RV manufactured today, but now focuses mainly on towables. 

     Since 1965 the main goals of the dealership have been to introduce the RV lifestyle to our customers and above all obtain the highest customer satisfaction possible. The dealership, along with the entire staff, understands that without our customer we would not exist. We do not claim that the products that we sell are always without flaws, but will stand behind them and do the best that we can to satisfy all our customers needs.
