I purchased a flat-tow kit and accessories from etrailer. They were shipped right away which was very helpful because I was planning a trip and needed to get the kit installed immediately after arrival. I checked with the installer prior to the merchandise arriving and found that the wiring kit was wrong. I had to order a different kit, from the installer, to meet my timeframe and they charged me $165 to return the merchandise. I would recommend going to the dealer direct if you're not going to do it yourself.
