We took our V10 Excursion loaded up from VA to WY 3x with no problems. The 8.1 should be fine, probably better than the Rx since it has the Allison transmission. The issue is would you trust a vehicle with 180k miles headed into the deserted west? I see Ford is coming out with a new 7.3 gas motor and if they install that into the Expedition, it may be a winning combo for you. I think any Ex out there will have similar miles as your burb.
Suburbans didn't get the Allison, but other than having less gears the 4l80E is a fine transmission.
As far as HD SUV's go it's about as good as it gets. Only other option is the Excursion as discussed.
