Took a load of scrap steel to the dump and got some scale time.

Unloaded the truck weighed 4300#s.
This was full gas, spare mounted, without me in truck.

It's a 1990 F150 Lariat 4x2 5.0/E4OD standard cab with 8' bed.

Just thought some folks might be interested in getting a general idea of weight!

I also noticed recently someone suggesting that a std cab truck is same weight as a 5.0 Mustang!
I knew in my gut that notion was WAY OFF...
Now it's proof positive that an F150 is substantially heavier.
Better than 1000#s!

 

My 96 4x2 4.9/E4OD standard cab 6.5' bed was listed as 3900# on the Ford paperwork, I would assume that's with empty tanks. That makes it about 4125 with full tanks. Pretty much confirms your 4300 for a 5.0 and a long bed.

 

Unless the dump is run by the mob.
In that case your truck probably has an actual empty weight of 3100#s.

 

When I carried a full set of tools years ago, my Bronco normally rolled around right at 6,000 lbs. I weigh ~225 and a full 32-gal tank of gas weighs ~225. The front bumper & winch are almost exactly 300; the rear bumper (with all the equipment in it) is probably almost the same.

 

Based on best guestimation of the extra gear, fuel load and what I'm actually dumping, my truck should go over the scales empty at right about 4750-4800 lbs.

1995 Supercab 4x4, standard bed, 302.

Other than the crap bedliner, tonneau cover, and receiver hitch, just about everything else is stock as far as weight.
