Show me one document from a single RV trailer manufacturer that states "The Recommended Tongue Weight of This Trailer is" using those exact words.

They are going to give you an Axle Weight Rating and a GVWR, they may in the broadest terms suggest a percentage range that the tongue or pin weight might need to be.... and they most likely will publish what the tongue weight was as certified when leaving the factory... but you will never see a document that might wind up in court that states RECOMMENDED TONGUE WEIGHT.

One can certainly extrapolate the MAXIMUM LEGAL tongue / pin weight from the sum of GVWR minus GCAWR, but not the RECOMMENDED
