That plate on the frame is not a patch/repair. That is a splice plate, straight from the factory. I'll bet there is one just like it on the frame on the opposite side of the trailer. It's a "C" channel frame made up of two or more sections on each side and spliced together with splice plates and huck bolts. See example
By the way, those pre-punched holes aren't there to save weight. Those have a folded innerward edge, they are for strengthening the frame so it doesn't fold over in the middle like folding a slice of bread.
The prepunched holes will "STIFFEN" this cheap frame somewhat, "strengthen" however is a real stretch of anyone's imagination.
Those prepunched holes in fact made an extremely weak spot where the highest stress would end up (at the axle and spring mounts).
The prepunched holes ARE a typical "feature" of "light weight" trailers. Punch out enough holes and use thinner material and you can easily save a couple hundred pounds of weight..
Manufacturer KNEW that this would be an issue and then placed that afterthought of a reinforcement plate to span a badly placed prepunched hole.
That plate DIDN'T do its job, did it?
The answer is NO, the actual frame under that reinforcement plate BROKE.
Can it be "fixed", sure, but it will never be as good as a properly designed frame whether it be an I beam, heavy "C" Channel or even a full boxed frame without all of those holes.
For the money and time, OP could buy the proper new steel have his Father weld up a far better frame from scratch.. But then you you still have the rotted out "box" to deal with..
So, why bother with such a messed up trailer, OP is going to put considerably more time (labor) and materials in this than what they could conceivably ever get out of it. But, hey if you like "giving" your time away, go for it, myself if I couldn't recoup enough money out of my work to earn a living I don't bother messing around with junk this far gone..
I know from my current TT, I worked every evening after work for 3-4 hrs on it plus full day on Saturdays (10-12 hrs) for 9 months, that is 1080 hrs and mine was in far better shape with a perfect frame.
If I was doing this to flip or make money and at the low end of what you would expect to be paid per hr of even say $10 for a yard laborer I would have to get $10,800 plus the materials of $5K out of my trailer.. Yeah, $16K!!!
If the OP was able to manage to sell this trailer for say $6K and they spent $5K on materials they would have a mere "profit" of $1K BUT, they would be working for nothing, that is not a profit when you consider the man hrs it will take.. In my case of 1080 hrs, that $1K leftover for labor is like working for a job paying you $.93 per hr!!
NINETY THREE CENTS PER HR!
I don't know about you or the OP but my "time" is worth far more than $.93 per hr.
That is the cold hard reality of a depreciating asset.
Even IF the OP could whip this into shape in say 100 hrs (unrealistic for this much damage) that would be like getting paid $10 per hr and now days that is nothing to live on.
Listen folks, used RV trailers are a dime a dozen, it was given to the OP because it was not worth sinking money or time in it.
OP can make more money quicker and with very little labor just by selling off the used parts, shouldn't be much more than a couple of hrs of work to remove everything of value and sell it.. Then burn the box and take frame to a steel scrap yard..
