My understanding of the newer ford internal reg altenators is that they are simpler to hook up, however the one everyone likes (the 94 up truck and mustang alternator, I have one in the Klogger, Seacreast has one in the Jeep and Garrett has one in the EB) is much more prown to failure with dust, mud, etc...

All that being said the stock ford truck alt is like 90 amps, which brings the suck when you run a winch! The 3G is like 135 or so, much better.
