i'm a bit late in responding, this forum doesn't get many posts and i think it's my first vist to it b/c i'm in the market for an excursion. anyway, in repsonse to the supercharge questions, NO, i would not agree with the suggestion to put a blower on the 5.4 in an excursion for towing. i have a lightning and they are 2,000 lbs lighter than an expy and rated to tow less. with any heavy towing you'd be building a lot of excess heat with the supercharger. i have an EGT gauge and with moderate loads with a dyno tuned TOW tune, the heat the blower generates under load and under boost while towing is scary. it would not be an ideal combo. many folks have added blowers to the 5.4s though. i wouldn't recommend it in this case though. talke to Mike Troyer about some of the basic mods to wake the 5.4 up. the 5.4 is a great motor. you may work it hard under load but it can take it. a gear change would be good as well as all the air in/out mods on top of a custom tune.
