I was promised that national vehicle would list my 2020 keystone Montana High-country fifth wheel on several web sites and would get results with in a couple of weeks and get weekly updates on results and handle all inquires and forward them to me for a flat fee of $599.00. They did list on several sites and I only got an update after the first week, and even after lowering the price I didn't get any response or any communications from National Vehicle. I listed the unit on Craigslist and with in 3 hours sold the trailer for full asking price. Save your money there service is a scam.
