There is but one single purpose for the RV trailer manufacturer to publish a hitch/pin weight. The regulations trailer manufacturers must abide (FMVSS) says they MUST publish a hitch weight. In your case itís purpose is explained in FMVSS 571.120 and says in paragraph S10.2: On RV trailers, the sum of the GAWRs of all axles on the vehicle plus the vehicle manufacturer's recommended tongue weight must not be less than the GVWR. If tongue weight is specified as a range, the minimum value must be used.
Once an owner takes control of the trailer the tongue weight is controlled by him/her.
