Been reading through the PSC Tech pages, one of which shows the reservoirs. However my reservoir is not shown, the -10 feed is on the side, -6 return is on the bottom on mine

Can you swap the fittings? Wouldn't be the first time you put something on upside down. 
Seems to be the case with the others...

lol nope. one -6, the other is -10 (welded).
In theory it's probably fine if it's full enough. If you suspect a problem you could have some turn the steering in the direction that will cause the cylinder to pull the most fluid (non shaft side) and see if it's drawing the fluid down below the fitting to the pump.
Otherwise sounds like something sticking to me. In the pump or maybe the steering box. Not sure if the box has anything that could do that.

Surely not belt slipping or pulley slipping on the shaft.
I should try it lock to lock and see how low the reservoir is getting. It would make more sense if I lost steering downhill as the feed to the pump would potentially go dry first in that scenario.
nope.

What about a small fuel filter or something on the return line?
The sticking valve theory does hold weight, and some debris from Moab is certainly an easy scenario to imagine.

Ford i believe does an inline power steering filter. There are also many options on the semi truck side as well as just running a generic 10 micron hyd filter and filter head.
I could add a remote oil filter, I've seen those used.
I took apart my reservoir at lunch and found it to be pretty damn clean.

I had something similar with my rear ORD springs. The driver side was lazy by a little over an inch. I thought it might be residual friction in the pack, but the lean was consistent over a variety of conditions.
Oddly enough, swapping packs side to side fixed the problem. Except in cases where the truck is twisted up after a tight bit of maneuvering, everything is level within 1/4". I was surprised that worked.

I remember you talking about that now that you mention it. My truck has always leaned a little here or there but it's noticeably leaning passenger driving down the road. I noticed it when I was driving and then the guys mentioned it as well.
Have you called PSC on the power steering? Who did the steering gear?
No I haven't called them yet. The steering box is freshly rebuilt from West Texas Offroad.
I'd suspect the box but I don't know enough about the internals and how they work.
I think the pump is a just a vane pump with a pressure/flow regulator on the outlet fitting.
I did a little more reading and found a couple posts about the same problem however the OP's never posted a resolution. One guy talked about the steering coming back when on the accelerator, Something to try next time. The responses from other members was a bad box, stuck valve in the pump, clogged lines or air in the lines. It's all back together, I'll probably call PSC and see what they say. I can also call west Texas Offroad, those guys seem pretty helpful.
Don't have time to look back and see what you used... what fluid are you using? I had to switch to a full synthetic (purple stuff) because regular fluid just flat out wouldn't last. Don't know why but that's just how it was. Probably doesn't help but I thought I'd throw it out there.
I'm using the swepco fluid PSC recommends. I've read that subpar fluids can cause all kinds of issues too.
It's never simple is it...
