Parker just sent these a few weeks ago. My trailer bunk setup was very unforgiving. I either ended up on the strakes or on the downward facing trim tab edges. I moved the center of the bunks to the 27.5," well inside the strakes, but that seems narrow and unstable. I am adding another set of bunks at 17" farther out on each side to split weight sharing and add stability. I'm in for about 250 bucks, but for that I should NEVER encounter a lifting strake, trim tab, or transducer (through hull or structure scan) upon loading, barring damage to a vertical trailer guide). The 8ft set of second bunks are short of the trim tabs
