I must have missed the part of that post about me being the trailer boss.lol Thought it said trail boss in the original and was confused even then as to why me...lol
I'm not an expert on trailers, but know a little about metal and being able to repair/replace it once it is full of cancer. I read the post Sereno had from the trailer company and find it to be full of great information on checking out the wellness of your trailer/float. I will say this when looking at a trailer,yours or a possible buy, take a screwdriver with you. Poke at any spot that looks fishy to see if it is weak and thin or rotted all the way through. If there are rust bubbles then poke it. Some of you are up north and deal with a lot of salt on the roads so I suggest you or someone you know climb under and poke away at the frame where the axle springs mount to the frame, springs mount to the axles and everywhere you can reach where the frame meets the body that appears suspicious. Look for bulges in the body as if someone has patched over rust with body filler. If it's a fiberglass trailer/float then push on the suspicious area to see if they did it properly to have stability.
I've turned down repair work on a vehicle from up north due to the amount of rot in the frame and body mounts. I don't have the time or means to take on such a project as that, but can handle things like a flat trailer or horse trailer with a lot of rot as it isn't as hard to handle to replace.
Guess I had more to add than I thought or drew it out with a lot of type..lol
