Around '92 when my 76 F250 4wd was on the road during the winter time a long nosed Kenworth had pulled off the side of the freeway to tighten down a loose strap & in so doing that he got stuck in the snow & angled shoulder of the freeway. The semi had a 40ft flat bed with steel tubing on it. My truck has a 460 with a 520 strocker kit which is putting 610 hp & 585 ft lbs of torque to the rear Dana 60 & hp Danna 44 with 4.56 gears & 35" BFG M/T. My truck has a NV 4500 5 spd ,so with all four tires locked w/ ARB Lockers & 4wd low & granny I was able to pull the semi back onto the more flat surface of the shoulder & into an area where the snow wasnt as deep.
Besides that being my largest tow ,my biggest load carried was with 2ft side boards & also a 2ft frt & back boards. I had 6.53 tons of 5/8 crushed gravel in the bed of it. YES a little over 13,000 lbs. The rear leaf springs are for a F450 with overload springs
My truck has been sitting now since Feb of '95 due to several replacement's of dana 60 rears not holden up to the power & tire size & the fact that I also have a broken front steering u-joint.
I also had to more kids since the truck has been sitting & also got a divorce in 2001
I plan to get me a Sterling rearend & up grade to a Dana 60 frontend some time-some year down the road.
I actaully built this truck from what was only a 73 F250 4wd frame,complete front suspension,front & rear drive lines,rear leafsprings, tranny & transfer case.
NO engine ,cab,bed,rearend,wheels or tires. In 3 months I gathered all needed parts to get the truck put together & on the road. That was in 91 when I only had 1 child & had a good paying job. 92,96 & 97 yielded 3 more kids & vehicle $$$ started to go else where
