Its hard to tell from the pictures but it looks kind of steep to me. It is. It is greater than the maximum manufacturer recommended angle, but less than the practical maximum.Just a guess.

Love the completed pictures and the photos of the trip. Thanks!!

You running 4.10's? Yes, still have 4.10s
You just went from about a 29 or 30 inch tire to about 33's right? I bet your mileage will improve some. Actually it was about 32" to a 33" tire, so not too much difference.
A .73 5th gear would give you 3.00's from the 4.10. It seems like you should be in the ballpark now. Plus the increase of tire diameter should net you a tick lower numerically.
