You should pull them all back out, and use the one labeled "RSRDC_SH15_V550", then the "RSRDC_V5xxx_Patch", then you can experiment with a few of those other small mods.
You can also do the "TriggerMaru_Overhauled 2-5", the "RSRDC_TMO_V502", and that same "RSRDC_V5xxx_Patch", and then other small mods.
What you have now is the RSRDC intended to go on top of
Real Fleet Boats, hence the "RFB" in the name. RFB can be fun also! RFB uses the stock campaign, so RSRDC adds a new campaign layer.
