It's heavier than that...........
An 86 XtraCab has a 5080 GVW and a 1400 payload (as I look at my 86 brochure)
That leaves an empty weight of 3680 lbs without anybody or anything in it (but full tank)
Gas is 6.2lbs / gallon * 19.3 gallons = 119.7 lbs
or 3560.3 lbs as you run out of gas (not including you)
I didn't mean to shave off some weight....
Well.. it's been almost ten years since I weighed it. But, yes as I recollect I was surprised that it weighed about 300 lbs. more than my 1985 shortbed. So, I can't find my little log book, but yes, I think it was close to 3500 + something?
I think my 1985 was 3195 with me not sitting in it and a full tank of fuel, 33" tires mounted on aluminum wheels, with 103" wheelbase.
This 1986 has 112" wheelbase and has a 17 gallon gas tank.
