Right at the edge???

Haha I actually did something similar with a 76 Ford F 250. Put 2 pallets of 2 X2 cement slabs in the box. Took it easy driving the 4-5 miles home. Mud flaps were dragging the ground, but the old girl did it with no damage.

We did similar to that with our old 70's ford crew longbox. Filled it with sand for the beach we made at the lake. Split all the seams on the bed and boxsides. Ah..memories.

You won't have to account for the fuel. That weight is already subtracted. The cargo max weight is the number for occupants and cargo carrying capacity.

The 1200# payload is probably optimistic as well anything you add to the truck after it rolls off the assembly line eats into available payload.
Last two trucks I have purchased had undercoating and Line-X applied at the dealer and within a week or two had a toneau cover installed and by the time I got to the scale to see my actual payload I was down a couple hundred pounds already.

I had a 2013 F150 with ~1400lbs payload and a lighter trailer 281BHS. I crunched all the numbers before buying the trailer and knew it would be close. The first time we hit the scales with my wife and two children under 3 we were within 32lbs of the rear axle rating. I would say the truck did fine but it was not a pleasant, relaxing drive.

We now own a F250 and life is good!

What's that saying about "too much truck"?
