Made it ok . Few minor problems with the truck . A/C started to ice over after a few hours hardly anything coming out the vents . Turned it off and after a bout a half hour it was fine again. May be to low on Freon or the orifice is slightly plugged or too small. It may be me but the 700r4 lockup wasn’t working correctly. Shifted great but up hill it would go in and out of lockup. Again may be me haven’t driven one with the 700 for 25 years. I just shifted into drive and it was fine . And it may be the 3:23 gears too truck was getting 15 to 16 in OD and it dropped to 14 mpg in drive . This is at 70 to at times 80 mph if your not going that fast they run ya over

So far I’m at 987 miles for the trip
