Swap bedsides or the whole bed?

[RPBurris]

So i put some money down on an 8' fleetside bed. It is in good shape, has no rust, floor is great, sides need a little work, and comes with a tailgate that is better than the 2 i currently have. it is hard to tell from my camera phone pics but is this a good start to a nice bed? I am not looking for a show quality bed but this certainly seems to be a good start. I will be getting rid of my bed in my avatar if i take it in a separate post.

If all i need are the sides is it easier to swap sides or just un bolt the whole bed? I would think the whole bed is easier?
