How are you putting both in parallel for the winch load?
I actually went to a triple battery setup... I still have a traditional ACR based system with two regular starters, and then use a DC-DC and a smaller battery for the small accessory loads like the fridge.
Also, you could consider separates from Victron Energy instead of REDARC. I think they have a better overall system.
DC-DC
Orion-Tr Smart DC-DC Charger Isolated - Victron Energy
MPPT Solar Charge Controller which is substantially nicer than the integral one in the REDARC. Phone application, bluetooth connected.
SmartSolar MPPT 75/10, 75/15, 100/15 & 100/20 - Victron Energy
Both are programmable voltages so you can match it to any type of battery you want, including lithium.
Victron makes really good gear... been using them for years in my custom builds.
Here is a good case study when looking at solar and self recovery from a flat battery.
