20 Seacraft trailer set-up questions

[Ed]

I have a customer who is purchasing a trailer for his 20 Seacraft center console. I want to set up the new trailer best as possible in advance before we go on the road for an hour to pick up the boat.

Here are my questions.

1) What is the ideal distance between the rear bunks (two measurements - front end of bunks and read ends of bunks)

2) What is the measurement from the towing eye on the bow to the transom? This will help adjust the winch post to ideal location

2) The forward bunks are self adjusting so probably will not have any much to do there but suggestions are welcome.

Thanks in advance.
