Two of my best friends in HS bought a new '76 or '77 F-150 4x4 when we were 18 and lifted it w/ big mud tires just like that. It was a twin to that truck except it was black. They used it for work, (one of their Dads was in the cement business), and even though they were making big $$$ for teenagers at the time, the truck was bankrupting them at the gas pump.
I so specifically remember it, gas was probably about the same as now in adjusted dollars in the '70s.
Didn't mean to be a buzz-kill, it's a pretty truck. It just really brought back memories.
I wish I could find the pictures of us playing in the mud w/ it in the infield of the old Donnybrook raceway during a CanAm or TransAm race in the summer of '77.
Hey, speaking of UFC, one of my good friends worked on an infomercial all day w/ Tank Abbot. He is producing it or something, he basically hung out w/ the guy all day and they filmed him. He called me about dinner time in stitches describing the day, first the boxing gym then the treadmill, etc.., then to the sports club for some weights. He wanted me to guess how much Tank could bench, I said I dunno, maybe 400?
Before he made me guess, he told me that the guy is in "terrible shape", I guess he just meant fat. The answer?
(drumroll)............,
495 freaking pounds, and he did it 3 fooking times!! 
Then he asks me, "is that pretty good?".......
