I have a couple pictures around somewhere... I'll add them sometime later when I get around to getting them up online an all...
In the bed I've had over a ton on several occations...not sure of the exact weight because the yard I was getting material from the one time...well...their bucket scale was broke, so it was somewhere between one and one and a half tons...
I've also packed the bed full of things that I have no idea what the final weight would be. Once I had a full-float D-60 rear, two heavy duty D-44 fronts, regular D-44 front, D-30 axle housing, ranger tailgate, three 33" treads, my cap and 75# toolbox on the back. I've also had a 7.5, d-35, two sets of leaf springs, one pair of coils, a BW 1354 t-case, a4ld tranny, 4.0L, 2.9L, and misc assortment of other items in the bed, topped off with a chrome pushbar, 80# bag of cement, 75# toolbox and a radiator.
For towing, I've dragged my 88 BII on a car dolly, my choptop stock on a car dolly, my choptop in it's current form on a tow bar, and my one buddy's YJ on a tow bar.
My Ranger came equipped with the heavier GVW package and I use it.
