as our old RV (and us) don't like crossing mountains... what is the lowest altitude going from the west coast to the east coast across the mountains. i was told that I10 is flat but elpaso is 4000 f...
Well, anonymous, "The West Coast" is 1200 miles long. If you have Streets and Trips, you could change the view to "Terrain Map" instead of "Road Map" and do it yourself, or we'll do it for you if you tell us where your start and end points are. So far, all we know is that your starting point is "anywhere". BTW, "Mountain Directory West" only describes roads with major changes in altitude. If your proposed route isn't mentioned in MDW, then you're good to go.
