Unless a flatbed is made of tinfoil.... it's going to be heavier than the stock bed. In most cases it's a lot heavier.
depends on a lot more than what it is made of... what all is on it? simplke or complex front board/headache rack. tool boxes, lights, side and tail walls or just a stake bd with wood sides. if you get an aluminum flat bed with ZERO on it, it will weigh less than a stock bed. but not by much. start adding the things people like on a flat bed, like storage boxes, nice headache racks and lights and it adds up REAL fast tobeing more. oh, if you have the coin for an aluminum bed with all that stuff... then you are better off than i am...
It just depends on the bed, but I would say an average steel flatbed could range around 1,000lbs heavier, roughly. I wouldn't know for sure as I don't have any pickups with flatbeds. As far as feeling it effect power....you bet. It doesn't matter if you've got a 500HP Dodge Cummins, if you know the truck well and drive it tons, you'll feel it for sure. When I have my Polaris Sportsman 4x4 atv that weighs 850lbs in the bed, I can definantly feel the weight. Above 500lbs and I can feel it, under 500 and I can't really tell. But, to give you an example, I can feel the truck heavier with three passengers riding with me.

I said I can feel 500lbs added to the truck. That is an average of 167lbs per person. 3 people in good health could easily average that.
