Your truck should weight less than 8,000. My 94 F250 4WD 460 E4OD super cab with long bed and a glass shell weighs a touch under 8,000 with both tanks full and about 600lb of passengers and junk in it.
Since yours is 2WD that should drop a good chunk. Wild guess is maybe 500 lb? The shell I think weighs about 500(eets a big one).
The weight I have is from a city dump scale.
Maybe the curb weight is listed on the door sticker?
I would assume that your truck is more than 4,700 lbs. More like 5,200-5,500lbs. My 94 F-150 4X4 reg cab, long box, 300-6 with 5 spd weighs in at 4630 lbs. Thats with just my tool box and about 100 lbs of log chains in it, so about 4,480lbs curb weight. My old boss had a 85 F-150 4X4 reg cab long box, with 351 HO, and C-6 auto weighed just over 4,700 lbs. Thats just the truck nothin else in it. A buddy of mine has a Chevy 2500 2wd, ext cab, long box, with 350/auto. Last time we hauled wood, his truck weighed exactly 1,000 lbs more that my truck after we unloaded, 5,520 lbs.
