An update:
I just landed in Amarillo. I did a solid 4.5 hours driving at between 47 and 52 mph. For the gentleman who has asked a few times now, and I have been ignoring, I am getting 6.875 miles per gallon. To be honest, I haven’t been paying attention until today. That is a good number, only 1 stop, all freeway driving.
I was surprised to see the temps at this stop though....
front diff 150
int diff 219
rear diff 145
front hubs 110
int hubs 125
rear hubs 105
trans 175
transfercase 185
I figured it would get to operating temp and stay there. To be fair ambient is about 70 degrees. It is about 85 degrees in the cab with windows down.
The truck did did not want to shut off with the main switch, shut down on 3rd flip.
I am going to let her rest for a few before getting back on the road.
Almost half way!!
As always, thanks for all your help!!!!
