I'm looking at 05-06 Expeditions and some have tow packages and some dont. The ones without have a lot of other options I do like while the ones with tow packages are pretty barebones. I am pretty handy with a wrench (put in my Magnum Powers blower on my 01 Lightning in the parking lot at my old apartment) so my question is, does anybody know what it would take to convert an Expy without a towing package to one with a towing package? I have seen what is on the older Expy's but on the 05+ models I see conflicting reports about what it has. Some say there is a bigger alt, others say a better tranny cooler and radiator. I tried figuring it out by going to Autozone and getting a "replacement" alternator, but the funny thing is there was a 110 and 130 depending on a built-in navigation system or not. There was also no difference in radiators. Are things "beefy" enough on the newer ones that the only thing possibly needed is a better tranny cooler and 7pin wiring? If so, that would be great because it would really open up my options. Can somebody who has experience with the newer models confim for me?
