I want the longest tiny house available. Will you make me a tiny house trailer that is 12.5 meters long?

Fredโ€™s Tiny Houses do not make tiny house trailers that are longer than 10 meters. Yes it is legal to have a tiny house that is 12.5 meters long but the maximum weight of the completed tiny house has to be below 4.5 tonne (4500kgs) when using electric brakes, so it gets very difficult to finish the tiny house under that weight limit when is it so long.
