I have registered my Warranty on their website, but no notification from Tesoro that this was received, but hope my purchase/SN is registered in their database, that's all, Ill take their word for it unless maybe I should call in or email them directly if they in fact have my Vaquero registered.
Anyone else has done this, as I did not receive a warranty card in my original box from the dealer where Tesoro did state that there should have been one. My receipt and my S/N was good enough I imagine.
