I agree, that's a lot of camper for a half ton truck! I wouldn't want to pull anything really longer than 31 foot on a half ton. My DBUD is 29'10" and is about perfect for a safe pull. In many regards, just because it can pull 11,500, doesn't mean that it should. Safety first, especially if you are new to towing.
