You have to decide whatís reasonable. A 4000 may work just fine, however, for longevity, a more powerful one may last a lot longer. My 22 footer has a 3500 pound jack on it. When it wears out, it will get the heaviest duty one I can afford...
Overkill Engineering is my game. Stuff thatís not working out at its limits lasts longer.
