Obviously depends on truck model but the last 3 trucks I've owned (all American brands), the process was remove belt, remove wires from alt, remove two bolts to remove the alt. Replacement exact reverse. Experienced wrench turner, maybe 30-45 mins at relaxed pace. Inexperienced, maybe an hour or so. In my case, factor in a beer or two and it was maybe 90 mins including clean up.

ADVICE: Buy the OEM replacement alt. Too many aftermarkets are crap.

Last one I did was on my 2006 silverado 2500. I wasn't in a rush, so I took it off on day one and dropped it off to an electric shop that rebuilds them. Picked it up first thing in the morning of day two ($90), and had it back rolling shortly after.
