See my signature below. I've had the Andersen Ultimate for about 10,000 miles across freeways and mountain passes and it goes great. Saves $ over std Fifth hitches and most important to me it saved 100 to 150 pounds of payload. It's design meant I also avoided the need for a slider. Do a search on this forum and you will find many positives.
