I ended up buying the 94a 12si model. I would've gone the 130 route but there was an issue with the clocking. I also bought #8 wire for the charge wire. Was going with 6 but that stuff is crazy expensive and #8 is what they recommended anyways so it should be good. There's not that much draw on the system anyhow. I bought a 4 fuse block and a couple relays. Now I just have to muddle through the installation.
