Want to replace my Coleman cooler/dry box with and actual dry box. Question is regarding the width. Current cooler is 35" wide and just touches the inside sides of the raft when in place. Most of the dry boxes I'm looking at are 36" wide. Will having the box fit snug inside the boat do damage? I wouldn't think so, but thought I'd ask. Fully inflated, a 36" box would have to be pushed into place whereas my cooler falls in and is slightly loose.
