Oh HULL no!

Something like jjBroc has?

I'm lookin for the thread with that picture and can't find it.
Can't see the roller in the picture of his that you posted.
But it don't look like I'm describing.
I like the lack of rollers on the trailer except at the bow contact with the trailer.

Trying to achieve this but without redoing your bunk situation and leaving the centering posts.

if it were me, I would raise the bunks

Sell that trailer and look for a good roller trailer.

I love my rollers and my friends do to.
They like the way I can power load and then they only have to crank about a foot of cable.

If you are using a steep ramp the bow might actually be hitting the cross members anywhere on the trailer, even between the bunks. You can move the bunks in some, buy some rub pads for the center of the cross members, or just get another trailer. I would try moving the bunks inboard some if you can, and if you feel comfortable with it.

Edit: I just looked at your pictures again. You defintely can't move the bunks without some major work and adding more stuff to the trailer, and I see you already have some bump guards on the cross members. Your only two choices look to be raising the bunks, or buying a new trailer.
