The title of the topic pretty much says it. Have any of you who use LS1 fans in your truck ever done any towing or hauling after you installed them? I am contemplating buying a set, but I read one retailer stating that they do not recommend using them in full size trucks because they were not adequate for towing or hauling. Also, has anyone run into trouble using the LS1 fans with the standard 105 amp alternator?
