Geez, after seeing pictures and video of my doing escalator I'm kind of bummed that I didn't try a bit harder. It really felt like I was a lot tippier in there then I was. Definitely trying it again next time, when I have my Hydro Assist working better and my exo on.
Honestly, I'm not sure what else you could have tried. You worked from being on the passenger door to being on the drivers door (at least as far as one can without actually leaving paint) and I'm positive that we had your rear tires on the same line as the rest of us. I know you're truck can handle it, just not sure what needs to be done differently than what you tried. The rear passenger tire seems to be the key, just not sure where yours needs to be.
You need to give us a list of the days/trails from your trip.
