10 Foot Bunks

[AZDave]

I had to replace my MC trailer 3 years ago. The Pacific Trailer I bought came with 10 foot bunks. I raised that concern with the builder and was told it would be fine. Today I noticed some gelcoat spider cracks on the left side right in front of the bunk towards the bow. Just a few. My camera not showing any detail. Could this be from weight bearing down on the end of the bunks? I know a lot of lifts only have 10 footers, but don't want this to get worse. Lifting one thing, trailering another. Bunk alignment looks good. Just 2 feet shorter than OEM.
