Re: Dead trailer, what to do?
clear your plans with your seller--he might not want a big operation going on in his yard, but then he needs to sell the boat. he'll be stuck disposing of the old trailer; use that as a bargaining chip. And do you want to go buy a trailer for a boat you are just looknig at--you might change your mind?
If you haul the whole thing away on a roll back you have more control and options. You could drive straight to a marina/boat yard with a hoist, let them pick it up off the old trailer and drop it on a new one--or into the water or onto stands. Will you be taking it into a shop for new boat repairs (water pump, fluids, check-over, fuel disposition, etc.)?
Maybe the seller will pay part of the roll-back (by dropping the price) as consideration for his not having to deal with the old trailer.
