Before I ask my question I just wanted to thank everyone here for this great resource. This is my first post but I've been lurking here for several months and the information here was invaluable when my wife and I decided to purchase a 1970 (or maybe 71) Boler.
The trailer is actually in very good and fairly original shape but it desperately needs a new axle. With that along with some other modifications / improvements I want to make I've decided to drop the frame out from under it so that it's easier to work on and restore. I've read everything I can find on what it takes and it all makes sense but I'm unclear on what to expect with the center dropped section of the floor. Originally I thought that it would just stay with the body when I dropped the frame out but now I see that it's riveted all the way around the perimeter to the frame. I don't know if that's original or something that was done later.
I'm going to have to remove those rivets one way or another but it occurred to me that it might be easier if that section of the floor dropped out with the frame. What i can't tell is whether that section of floor is actually glassed in from above in which case I'd want to leave it there and remove the rivets ahead of time.

floor is all one piece, and yes it dropped out with the frame, I am no expert but sounds like it was a later modification.
I unscrewed 4 major bolts around the corner areas, then there was a line of about 6-8 smaller screws running down the length directly above the frame, one was hidden inside the closet beside the wheel well under the lowest shelf, these also screwed into the frame.
I raised the fiberglass "egg" and the frame dropped out.
realigning it up again was much easier that I expected.
Note I did not enter the "egg" while it was jacked up at either end as the floor might not support your/my weight
