This is an old thread, so your problem and saga continue. I never did see the name of the manufacturer but not to stand behind your product is an admission that the problem, or the solution, it too big for you to handle (and further that you have no integrity). The construction is clearly substandard, and if they are still making trailers, I can’t imagine that they have not modified their assembly method to address this problem. If so, they should fix yours similarly.
There are likely several problems including screwing into plywood end grain, not enough glue, not enough screws. The thermally induced stresses IMO, and maybe also a contributor, but shouldn’t be a show stopper if the rest of it had been done properly. Really though, this shouldn’t be too difficult to fix, which makes the manufacturers refusal to take care of it all the more egregious (or are they just not very clever?).
If possible, you will need an angle that runs the length of the tear. It could be put on the inside or the outside, but if you put it on the outside (underneath) it can also be used to prevent the ingress of water [if installed with sealant]. If your frame is steel, then I suggest a light-weight steel angle – maybe 16-18 gage 1x1. Pre-drill holes every 6 inches or so on both legs. Squeeze the sides together using some long bar clamps (or by whatever means necessary) then install the angle with strong (polyurethane?) adhesive or something like Sikaflex to join the sides and floor. Screw the angle onto the floor and onto the side using the longest wood screw that you can get that won’t poke through the other side. BTW, you can also use that adhesive between the side and the floor as well as on the angle.
If there is no room from underneath due to a clash of the frame and the ‘new’ angle, then you can do it from the inside, but I’d also put some sealant in the corner [if you can get access] from the bottom. If you have to go through the inside, then you don’t have to worry about dissimilar metals and galvanic corrosion and you could use aluminum (probably 1/8 inch thick – at least that’s what’s probably easily available).
And lastly, I would frankly print the manufacturer’s name. Their behavior is unacceptable. If I remember reading correctly when you first started having trouble you were only 90 days out. If they can’t build a product that they can stand behind for a year (at least material and quality of workmanship), then they should find another ‘hobby’ – this one ain’t working out for them.
