I did take that route. It was awesome!
I am sitting in Moab typing this
Did the family proud. 2500 miles, 2500 lbs of trailer. No problems, sitting in Moab posting pictures...lol. I swapped out to a new prop shaft and did a drain and fill on the tranny in KC,MO. Running around 11-12mpg. Shell gas is the way to go, hands down. Burns very little oil with shell, if I used something else, I was adding a quart every fillup. I have used 6 quarts of mobil 1, this burning oil thing is getting pricey, but it seems shell gas is the answer, when I can find it.
Gonna hang out here until Tuesday. Probably go rafting on Monday.
