I am getting a new 1200 lb/12k Equal-I-Zer this week. My trailer weighs about 9,000 lbs loaded. The Equal-I-Zer calculator said that I needed the 1400lb/14k hitch. I went with the 12k because I might be downsizing in a few years (I want to get a new Lance). I have been towing it with a Reese Dual Cam with 1,000 lb bars and 10k rating. I have never been happy with that hitch and it is 8 years old. This is my 3rd trailer that I have used it on since 2006. I realized that my current trailer was probably too much for this hitch, but I really have not pulled my big trailer that much with it. I used it on this camper because I already had the Reese hitch.
