Thanks! The Poncho Springs recommendation seems lower (9000’) and less grade! Still not sure if our 99 V10 Triton can support the lack of oxygen (my husband’s concern). Do you know how the road conditions are there…good pavement, wide lanes, passing lanes, not too many sharp curves, etc? Also any info on how we can easily see road grades would be awesome! I keep looking them up road by road, pass by pass. Or use google maps to see elevation numbers (which I need a magnifying glass to read on my phone!).
