I have an '87 Bayliner capri cuddy It's 17'. I would like to get a new trailer jack for the trailer. All I ever seem to be able to find are 1000 LB. capacity. Will this due? I would like to get one that swings up. Does this change anything? It is the original trailer. Maybe there isn't even enough room to swing to the jack up.? Like wise with the tounge, what would the correct capacity be? Thank you.
