John, that was a great write-up on the GlowSteps -- well done!
For whatever it is worth, I am also a happy GlowSteps camper -- we do a lot of boondocking in rough country, and the GlowSteps can cope with difficult situations.
But if I understand the OP's situation correctly, I'm not sure that GlowSteps would solve the problem of a very narrow site, with the bottom of the step an inch from a block wall. I don't know of any steps that would handle that issue.
