Thanks for the replies. It doesn't sound like there are any really great solutions.
The reason I took the dry box out in the first place was due to an injury to my wife's foot. We were running the Alpine Canyon of the Snake River near Jackson. She was riding on the tube in the stern behind me. We went through a rapid and the floor dropped briefly. She was bracing against the box and her foot slid under and became entrapped between the floor and the box when it returned to normal position. I heard yelling behind me but didn't think anything about it because we were in the middle of a rapid having a great time. Then she started hitting me on the back of the vest and I turned around and saw how much pain she was in and saw her foot was entrapped. I stood up on the floor of the raft and pushed it down and freed up her foot. It was trapped for about 5-10 seconds. Her foot was very painful and swollen. It had been crushed between the aluminum box and the drop stitch floor. She had difficulty walking for several weeks and it continued to cause her pain for about a month and a half. She did not want to get back in the raft until we took the dry box out. AND SO THAT DRY BOX HAD TO GO! FAST! Now it's full of camping gear and as I explained previously, I kind of like it. I did put a drop bag under the buckboard, so I still had storage.
I called the DRE people today and they said I'd have to add 1/2 inch spacers on the front and back of the box as well as change the tab height from 5" below box top to 3". I don't want to screw up my box with the required modifications. If I do get a DRE seat, I'll never use it on top of the box. I'll take it off to use the box. IF, I end up going that way. Maybe, I'll just have another buckboard made. Maybe, I can figure out a way to turn it into a 2nd table. I like that idea.
Maybe I'll get an action packer and sit on the box all the time. I'm just worried about a repeat on my wife or one of my kids. I use the box on multi days. It's not a problem then because the back is full of stuff and no people are behind me.
If anyone has a suggestion, let me know.
Here's how the build is progressing. Attachment 11234
