Yes, please post some pic's of your improvements to the trailer. I'd like to see the bunk changes.

PS: On my Trailex 200S, the forward bunks are under the gunwale (without adjustment), and as you can see on the picture above, the rear foam blocks extend from the cubby to the stern. As long as the rear trailer bunks 'catch' the foam blocks, your fish and trailer should be OK.
