I painted the front fenders separate from the inner fenders. I built a stand similar to the attached (more scrap laying around

) and used it for one front fender. The other one I used a sawhorse (ran out of scrap tubing.

) I also used the sawhorse and it's twin to support the nearly fully assembled bed for painting. The inner fenders and other miscellaneous stuff got painted semi-gloss black (so no need to mask off anything if they were painted attached to the front fenders.) EVERYTHING on my truck was painted separately (It shows in a few places, but not a big distraction.) That commercial paint stand pictured is available for about $40, but would probably cost another $40 to ship to me.
