Had to put my plans on hold. Now ready to go. Help me design my system please?

I am hoping I can get some forum help with designing and installing my system. I think I know what big components I need but I do not know the exact other parts and also about how to connect it all together. Maybe first I will list what I think I will buy so far (obviously feel free letting me know if I should get something different)
- Panels - 4x 100w panels from Lowes wired in parallel because the distance between my panels and batteries be around 15-20ft? https://www.lowes.com/pd/Grape-Solar-1-Module-41-0-in-x-27-0-in100-Watt-Solar-Panel/1000597657
- MPPT charge controller epever. https://www.amazon.com/EPEVER-Controller-Lead-Acid-Batteries-Discharging/dp/B07KW5W49J/ref=sr_1_8?dchild=1&keywords=solar+charge+controller+mppt&qid=1589163564&sr=8-8&th=1
- Inverter Magnum CSW2012.
- batteries: 6x Duracell GC2 sealed. Making a 12v system will give me I believe 645ah.
- MT50 monitor.
Design notes:
- I own a honda generator 2000. Which I will use to boost my system if need be. I also own IOTA Engineering DLS30
- I want a dedicated wall plug of 5v usb to charge phones and such.
- I need a dedicated 12v charger for my dewalt batteries. I saw they sell one that plugs into the car lighter? can I incorporate that one in my system?
- Run power to the fan in the outhouse. a 12v dc fan that is unless easier to run ac?
General questions
- I am assuming that whatever trailer I will buy I will be able to wire my system to feed the 12v from my batteries directly and my ac from my inverter directly to camper's ac system without too much complications? is that true?
- I want to have a few dedicated usb wall ports with 5v and 2.1 amp (or similar) that will run directly from my batteries to charge our phones and tablets. Is that something worth doing for the power savings? I will charge two phones and two tablets each night.
- My place is in upstate NY. Not 100% sure I will go up to the cabin in winter but if I am. Should I always bring my generator to charge the batteries when I get there then before leave so they stay in fairly charged mode?

It takes a lot of power to charge the better lithium tool batteries. Why not charge the phone with your cars 12 volt outlet? Keep the solar system simple though you sound like you know what you are doing.
Michaelk - I would love to buy cheaper panels but so far I have not been able to find any online that are cheaper... Maybe you can steer me to the right direction?
Can you please elaborate on why I should go 24 vs 12? btw I cannot go grid tie. I don't have power on my land. If it just to run tool then I am not sure if that is worth it for me. Only tool I use continuously which is wired is my miter saw which I can always power with my generator if I need to for that once in a blue moon usage. This is a weekend cabin.
Also, I have read that unlike lead acid, AGM are maintenance free and require no equalization. Even read that they are better for seasonal cabins because of that. I was looking at the sam's club gc 215ah 6v batteries. which at $90 a pop are a great deal but I am willing to pay more for that ease. Any recommendation on where to get inexpensive agm's?

your 400w of panels can provide 13A of charging, a bit on the lightweight side, but 2 more panels, for a 3S2P solar array with a decent 30A controller, will give a fairly simple but effective system
