The problem with tongue extensions is you can't extend a trailer tongue with off the shelf, bolt on parts. To do it "right" you need to have the extension properly designed for the trailer and properly installed by someone skilled in the art and science of welding. It's not something you can just do in your garage with a $90 Harbor Freight flux core welder.
Absolutely correct.
Rather than modifying my trailers my solution was to sell the old trailers and custom order new ones with an extended tongue. The trailer manufacturers had no problem with that, and the added cost for the tongue extension was only about $100.
