My 03 EXP came with a tow hitch and a 4 pin and 7 pin connector so I assumed that the truck was equipted with a tow package. Would that assumption. be correct or is there a heavy duty version tow package as well. Dealer doesn't seem to know but mentioned that there where 2 sizes of tranny coolers. I don't know if there's one for the 4.6 and one for the 5.4 or if there is a bigger one. Any towtug owners out there who know?
