Inverter/12volt-24 volt question

Hi,I have a tundra 24 inverter that I took out of my Freighter semi and am installing in my tt.
I am taking out 2 6volt batteries and repacing them with 2 12volt bateries.

The 2 12V batteries will not have much more run time than your current 2 6V batteries. Depending on your load, 4 6V batteries would be better and I will get they would live longer !

Your battery charging system ( converter and solar) will be for 12v. You would have to do each 12v battery one at a time with the converter. The PWM solar controller might be one of those that can do 24-24 or 12-12.

An MPPT controller has a buck converter so it can be used as the DC-DC with 24v input and put out 12v but has amps limits depending on its amps rating.

Properly connected (two sixes are wired differently than two twelves at the batteries) there will be no difference with any 12 volt appliances.

Yes, you'll need a DC-DC converter to get back to 12v. Victron makes good ones. And you'll need a 24v charger to do it right. PM me.
