yikes I knew it was heavy but didnt know it was that heavy. That explains the sore back. Yes the diamond plate went back on the trailer. I am repainting everything red, as my landscaping trailer is red and want to stick with the same color theme, and my truck is red and white. I repainted the lower part of the trailer today, installed the new wood floor with pressure treated wood, put the diamond plate back in(with 2 other guys) and painted the diamond plate red as well. No pictures today as it was dark when gave up for the night. all is going well.
