Thank you for your very thorough recommendations.
Victron equipment is highly rated, although expensive. There are many alternatives now such as EG4. I like some of the newer all in one units now coming out.
I already have some equipment on my travel trailer that I can reuse possibly, a Renogy DC DC charger, a 4000 Giandel inverter, lots of various gauge welding wire, a Victron Smart BMV712 which I love the Bluetooth monitoring, etc. I won't be reusing the 4 Valence lithium batteries but will upgrade to newer batteries, or the 4 Rich 190 solar panels, or the 2 EP Ever solar controllers.
I plan on phasing in the installs a piece at a time.
1. Get a new AGM chassis battery
2. Get 1 or 2 new heated, or low temp cutoff lithiums to replace the 2 house batteries under the steps.
3. Figure out how to disconnect the chassis, house boost function.
4. Get a PD lithium replacement for the WFCO converter charger.
5. Add the dcdc charger and 712 shunt.
That will be the initial install. After that, I'll consider a separate lithium install to run the AC side of the coach, and eventually solar.
There's a YouTube and site out there called 5112 by Mike Mas that has the AC, DC systems separated, very interesting approach.
Anyhow, thank you so much for taking the time to reply to my post and for your recommendations.
