New to Solar. Need help building a system for my RV.

You are trapped in a 12 volt box you put yourself in. You do not know anything other than 12 volts which is why you choose 12 volt batteries when you should be using 2, 4 or 6 volt batteries for the capacity you need. You failed to do research and homework first. Now you are going to spend a lot of money needlessly. You wil be replacing all those batteries you bought in a year or two. If you had done your homework they could have lasted 4 to 6 years.

You don't have to rub his face in it as well. OP is new and trying to figure things out by coming here for help. I am new to solar too. You provide helpful and valuable information to other members, but there is no need to use this tone. My two cents.

. Just keep it classy.

Please keep your two cents in your pocket. Keep it calm.

What do I replace, what do I replace it with, and in what order?

If you already have the equipment listed, you use it until the batteries give out, and replace them with a proper set of batteries.
