I took my 86 SC F250 (8600 GVW) to get weighed with spare out, tailgate off, both tanks about empty and me out. Weighed in at 4780. That was in Nov 1994. Classed as "subn"
That's an interesting way to get below 5500 lbs too...
My '01 SD weighs under 5700 lbs according to the title.
It weighs 6800 lbs with me in it and about a half a tank of gas.
Without the seats, tailgate, spare, etc, there's no way I'm getting that thing below 5500 lbs
It's a 4x4, so a 4x2 MIGHT have a chance.
