21 or 23 trailer bunk question

[bj]

Thanks for the info. I had talked with a trailer sales and service shop about them doing this for me and had decided to let them do it but then he says I have to have the boat off the trailer. How the heck can they know what size and length bunks to use and the distance between them without the boat. I must be missing something. If I have to take the boat off the trailer I may as well do this myself. Thanks again.
