I have to agree with pwb01 because I noticed on mine earlier where that the bracket was not sitting square/ vertical. I knew something was up. If you look underneath you should see a tin (of sorts) floor. I took a grinder to that tin and opened it up by folding back a flap of sorts and exposing the 2x2 beams. I know that sounds scary and may sound like a lot of work but after all look what you found. Rot is rot and it won't get better. Question: if it's rotted there how far along does the rot go?
You need to find that out and cut the floor back beyond that rot. You need to see where the structural integrity joins up and replace what you can.
As an FYI I removed all those wood screw lags and replaced everything with 2 1/2 to 3" stainless steel bolts nuts and flat washers. I used the flat washer to distribute the pressure of the anchor better along the existing wood. I still had to open that tin floor below and inspect what I had for dealing with. I guess I was lucky.
You must close up that floor, bend it back and screw a do-it-yourself fastening. Then put some roofing tar over everything to prevent water/moisture from getting in.
Using the wood putty, the way you described, is superficial and does not address the initial problem.
On the brighter side you may have had a water leak near to where that braket is anchored and over time that immediate area rotted.
If you open up the floor underneath you might see rot in the immediate area and in good condition in either direction from the rot. If that's the case things could be fixable. Take another piece of 2x2 that is much longer that where the rotted ice is and bolt that into position along side of the existing piece. Framers use this method on rotted floor joists in old houses and I think it's called "sistering". as in brother & sister.
To save your trailer you might have to bolt through the siding but since you already have damage there now, by adding a shiny piece of aluminum or painted metal you might save the day. Looks like you or someone else drilled several holes as a trial and error to find a good anchor spot.Take things slow and easy and one stage at a time
Maybe some of the other members here could feel free to agree or disagree with my approach. Is there anyone that has had severe floor damage as Rivertrails mentioned?
EDIT: Btw cut the old rot out and insert new wood for that length THEN sister the new piece attached to its side. Say your cut out rot is 3 or 4 or 5 inches. Replace that and then sister at least double that to each side and bolt. Don't forget your dealing with weight so you have to make sure you're building something strong to deal with that weight
