This gives a bit of redundancy and convenience in keeping everything charged up, at a reasonable cost
The main RV system will remain a separate 2800W solar powered, and those batteries are going to be what budget allows.

I have 3 small systems running Renogy charge controllers with no problems so far. The campervan has been running for 7 years now.
To bad they dont make a 48v version of that dual DC - DC. To charge my 48v house batteries from the alternator Im going to have to go through a 12v DC to 120v AC inverter. (Which I already have so i might as well use)
I bought the rest of my Renogy components during their 1/2 off Black Friday sale last week
