putting on floor tomorrow

[ArtMini]

ok heres what I have planned for my floor in the morning. 3/4 ply bolted directly down to the C channel frame. Since its a bolt together frame, and I already welded all the joints, I'm going to take out all the top 3/8 hex head bolts and replace them with 3/8 carriage bolts. I'll counter sink them slighty so the heads are flush with the floor. I'm planning on using roofing cement to coat it underneath. It claims it dries to a rubbery texture which is what I want, I think, how does this sound?

If it were me I'd go to the local FASTENAL Location in Mass. and buy some elevator bolts. They don't need to be set as deep as carriage bolts and the head is flat and wider. Danny

Art Mini,
I don't know how far apart your supports are on your trailer, but if they are as close as 2 feet, you might consider using 5/8 instead of 3/4. I was also going to use 3/4 material, but I started thinking about how hard that was going to be to handle by myself on a windy day. I went for 5/8 tounge and grove. I have been crawling all over my trailer and have found no give at all. (and I am pushing 300#)
Good luck on putting in your floor!
Jim
