Lithium Install Questions 2017 View 24G

[YTDave]

I realize and appreciate that this subject has been battered around extensively, but...
I have a 2017 Winnebago View 24G. It has a 100 watt solar panel and a Zamp ZS-30A charge controller. There’s a PD9245C Converter/Charger that apparently looks after a couple of 6 Volt deep cycle batteries. I want to ditch the deep cycle 6 volt batteries and install a couple of LiFePO4 batteries. I do not want to have these two Lithium batteries being charged by the vehicle’s alternator because I don’t have the skills or knowledge needed to wire in a DC-DC charger. Between having a PD9145ALV Converter/Charger to charge the Lithium batteries when I’m on shore power (which is most of the time) and the solar panel, I suspect I’ll be fine without having to spend time, money and a great deal of frustration trying to do the DC-DC project. With that in mind, I simply want to disconnect whatever it is that causes my alternator to charge the house batteries that are living under the stairs. Anyone out there want to take a stab at trying to explain what it is that I’m supposed to do in order to make that happen? The idea of setting my RV on fire is just not all that appealing to me at this time. Thank you in advance for your guidance and wisdom…
