Only difference is that the OEM roof cargo bars are not long enough to do what I did. This way I get to put the box and ski clamp.May I ask what are the advantages of the Thule over the OEM roof cargo bars ?
My 22 Expy has the OEM roof cargo bars; and I am planning to put a 60 lb Yakima cargo box up there . Wondering whether I need to buy the same Thule too .
