Just thinking a little ahead here; me and my buddies were thinkin about filling the bed of my truck (short bed, 5.4, 2WD) up with water this summer....effectively creating a 'redneck pool.' That's an enormous weight in the bed
I calculated that if we fill the bed up with 16 in. of water, that would give us 43 cu ft = 336.6 gal = 2810 lbs
So the water plus ~600 lbs of people in the bed puts the total payload at ~3500 lbs, which the door jamb sticker says id the GAWR for the rear.
Having as much weight just in the bed
as the whole axle is rated for should be OK right? I mean, it is a ford
. Keep in mind that we wouldn't be going very far, and probably wouldn't even go past 10 MPH. You think this would tear up the axle too bad??
