Can't decide on a bed, any thoughts?

[amullis]

I am working on a 1971 Chevy 3/4 ton 4x4 and I have gotten the frame finished and have the body sitting back on the frame. I have a long box that is in great shape but now I am not sure if I want to use it. The purpose for the truck will be for both work and play. I was talking to a friend a few days ago and he has a 71 C/30 that came from the factory with a flat bed on it. He has since converted it to a dump bed and said that he would sell me the original flat bed for $100.00. This is what got me to thinking!!! Originally I was going to run about 10" of lift on the truck and a set of 38s or 40s. Now I think that it would still be cool to run the 10" lift and 38 or 40's but duall rear wheels and the flat bed. I would love to see any pics that you guys may have or hear your thoughts in reference to what I should do. Either way I think it will be a cool old pickup!
