My truck really hasn't been worked hard since I've owned it. I think the most I've hauled was a 500 pound load to the junkyard. It was just aluminum, it was sofit, facia, and gutters from a little house. I had a stack of aluminum that was even with the top of the cab and realized my 8 foot bed wasn't quite big enough. Ended up putting some in the tool box, behind the seat, in the floor, and on the seat.
Other then that I've hauled maybe 10 sheets of plywood, about 4 rolls of felt, and a half square of shingels. And that was only because my dad's trucks weren't empty and mine almost always is.
Not afraid to use my truck, just haven't really had to. Looks like I'm going back into construction a little, but I doubt this truck will be used much. For work I would be using one of my dad's trucks.
