I thought about this when I re-did the bed in my '66 Chevy C10 Looooongbed. I ended up going with White Oak for strength and the White oak is more pleasing to the eye. It also depends on the type of wood you use. If you use White or less expensive Red Oak you had better upgrade the suspension due to the weight. If you use a more soft wood like Pine or Fir... it's probably 1/3 of the weight. The real clincher is what you plan to load in the back. Pine and Fir are going to dent like a piece of cardboard while the oak is like... oak. Hope this helps!
