I'm already highly considering it but I still belive/know that the ram isn't the issue.
Here me out, I'm not arguing or denying yours or anyone elses superior knowledge of Hydraulic systems by no means, but I ran this exact Orbital and Ram on the Mountaineer which was heavier, had 42s with same wheels, same axles, welded f&r, and it turned perfectly fine. Now it had a Ford Pump (whatever kind that is but obviously different), single basic cooler, 3/8 return lines and these same type of hydro lines with fittings made at NAPA so I know this "mis-matched" system is not perfect but I know it works...it's proven itself in the other rig I had, that's all I'm saying.
And the Mountaineer pump I didn't even mod it or no big resi, just factory pump with little tank so probably half this amount of fluid and still ran basic power steering fluid mixed with ATF I'm sure
