all the wood, that is floorboards, inside the bed, roof bows, were painted body color. The underside of the bed wood was dull preservative black. There are other details regarding body bolt color, overspray, etc, available in the paint and finish guide. my info came from 2nd edition. the 3rd edition might differ in some respects. if you really want it correct to the latest stds, you should get the 3rd edition.
