A real run what ya brung kinda guy. Pretty cool. Got video of that pull?
I don't, his wife is the video person but she had to run the store while he went to play. That 'ol truck is a sleeper, when we run together I stay in the slow lane

When he hits the propane, the stacks blow black smoke, roar and stinks

With everything set on kill, he runs about 550/1100.
He is such a blind loyal Ford fan

I have a Dana-70HD, disk brake, 19.5 wheel, 4.88 limited slip axle out of a GM motor home. He will not let me give it to him. He would rather run his 'ol D-80, 16" wheel, 5.13 geared, disk brake and limited slip axle....He overloads that poor truck horible but it just keeps on a haulin but the tires don't last anytime at all.
The truck is rated 15k GVW, it weighs 12.5 empty, so load up a full size 4 door long bed diesel pickup and do the math. The bed is too short (19') it really needs a 21', all the weight goes on the rear axle now.
