Good!
Are the batteries part of the new system or where they part of the rv system?

I’m trowing away the cheap battery that came with the trailer and replacing it with 3x drive motion 75ah AGM batteries. Initially the only battery was at the front of the trailer near the propane tank. I’m puting everything inside under the table seats

ok so new batteries replacing existing batteries, confirm?
And the rv system should work fine with the replacement batteries?

Correct 3 batteries replace one cheap battery
It should yes. I’m bringing the fuse that’s outside on the frame closer to the batteries and reduce a good 10 feet of battery wire

Cool then I will assume the batteries are part of the legacy system and all should work well.
The only integration between the new part and the old part is the share they same set of batteries.
Now for my suggestions.
Starting with your first published diagram
1. add a disconnect switch between the 100 amp fuse and the fuse box.
2. add a quality breaker of appropriate amp rating between the main solar panel feed and the solar charge controller.
Observations
You will have 2 ways to charge the batteries.
1. the wfco converter when connected to shore power.
2. the solar panels whenever there is sunshine and the breaker is closed.
Depending on how much current the batteries can tolerate you may need to manage this.
IE only use one charging method at a time.
Is that clear?

What does IE mean? I planned on turning off the switch when I'm not using solar.
Do you consider when the TT is connected to the car while driving? I guess this transits by the power centre?
This is exactly what I needed as an answer!

And finally, based on what you said earlier, both 100 amp fuse on my first diagram should be replaced by one of those ? https://www.amazon.ca/Bussmann-BP-C...id=1584056113&sprefix=bussmann,aps,176&sr=8-3

Dude you are killing me.
4 AWG wire vs 4/0 AWG wire
Ok lets back up. You are just integrating one of Will Prowses blueprints into your exisiting rv setup, yes or no?

There are only 2 simple additions to your first drawing.

It makes sense. I appreciate your time and I thank you very much. I hope other people will learn from you like I did.

4 AWG wire vs 4/0 AWG wire
You say converter, did you mean inverter? You mention 6 awg wire, did you get some of that as well? The 6 awg is what’s already wired to the battery. What I mean by the converter is the electrical box with the fuse (WFCO wf-8995pec). I’m installing a separate 600w inverter so that I can run one...

OP the picture in the linked post does not look like a fuse.
I can't really say with certainty because of my poor eyesight though.
I'm worried that the existing rv setup is not safe.
I don't trust any of the existing design and implementation based on that one picture.
Also I can not take any responsibility for any of the things I coached you on.
I suggest you get a pro to check the entire job.

I'm not asking anybody to take responsability on anything and I appreciate the help. Like I said, this thing is going to the trash and I'm taking everything inside. Anything I have done and will be doing on that new trailer is way better than what the manufacturer has done unfortunately.4 AWG wire vs 4/0 AWG wire

If the manufacturer did what was in that picture then everything is suspect.

Two things ... TemCO (on Ebay) makes GREAT copper wire at a good price .. we have NEVER had an issue with their stuff at all ...
And OP if i understand you correctly u you are going to get 3X 75aH AGM new batteries??
