Big Al, I agree with the winch....since most of the time I load and unload by myself anyway...someone wrote earlier about adding extra length ramps, etc....IF the trailer has a last 4 feet of dropping dovetail bed, the Viper makes it up and over readily, with a winch, you definitely have to be careful loading, you may think you are on level ground and once the car starts moving forward into the trailer, the tongue weight takes over, the front of the trailer lowers some, now the car starts rolling freely to the front and there isn't much you can do about it except if you have your winch controller in your hands and walk alongside the car as loading and if in an emergency, reach in the open window to grab the emergency brake...I like to park the trailer with a steady up hill design and then it makes unloading easier as well...whenever I am around trailers, I also carry a rag in my back pocket and IF you need to throw it under a wheel, it may help to work as a chock if the car starts freerolling, also I added black electrical tape on the left side of my trailer's floor,(have a black/white checkered floor in my trailer so it blends in nicely) and it marks exactly where I want the wheels on the left side to roll into the trailer as I walk and winch the car into the trailer and therefore I don't have to worry about the right side hitting the trailer wheel cover ...just my $.02
