Well, I have a regular bed on my truck and my dad has a flatbed on his farm truck. I really like the looks of the factory bed better, but flatbeds can look really good too. Especially aluminum ones. They look particularly good on regular cabs and regular cab dualies. A little odd looking on supercab and crew cab trucks. I replaced my bed with rust free bed from texas when I bought my truck. By the time I bought the bed, had the dents fixed and then painted it and the tailgate, I coulda bought a nice aluminum flatbed. Now I have to baby my truck and hate hauling anything in it or helping people move or anything because I don't want to dent or scratch my paint job. My dad's flatbed is awesome! there is way more room, it's longer and you can haul so much more and don't have to lean over the side to get stuff. Plus there are places that you can strap to. And if you buy aluminum you don't have to worry about scratches or rust. I guess what I am saying is if I was to do it over I would probably get a flatbed. People are always worried about losing stuff, but you can put an empty 5 gallon bucket on the flatbed and go down the interstate and it won't move or go anywhere. However, we do have 2x6" sideboards just incase. That's my 2 cents.
