Per your photos, I was able to locate the sensor on my coach just in case future replacement is needed.  Limited access for sure and an inspection mirror was needed.  I'm guessing you just had to reach and feel your way through the replacement?

A 7/8" crows foot would work if you could fit it in.  Would more than likely have to be ground down.  The NOx tool can be had for less than $10 at Harbor Freight etc.  I suppose a 7/8" flare nut wrench may also fit.  Not much real estate available in there.  The normal oxygen sensor socket is too short for this sensor, at least the ones I tried.  I'm on the road, most of my specialty tools are not with me.

Most auto parts stores, AutoZone, O'Reilly's, Advance, etc. have loaner tools. That's where I got the NOx tool.
