I decided to stay with what came with the vehicle until I experienced how the batteries performed on enough trips and if the solar can keep them topped off in the winter while my WiFi, security cameras, spyder panel, and CoachProxy create a constant draw. I'm using CoachProxy to monitor my batteries remotely while in storage and waiting to see if I reach a point where it alerts me.
I watched the RVGeeks on YouTube recommend swapping solar or batteries, but not both at the same time as to learn how each change performs on it's own. They picked batteries first. I picked solar first as I needed it added new anyways.
If you swap, please let us know how it works out.
