Errrr, no.
Towed 3 ton for 50Km this morning (D1 Tdi and big trailer) , did it well but I'd reckon 4t is a 'sometimes' load, rather like Pizza, or Doritos and cream cheese dip....:o
Even the big Suzi needs low range with the LT95 gearing on hillstarts with that weight on the back, or you'd get to smell some unpleasant smells.
