I farted so so much the other day and oh my god did it smell, I think I killed my cat too.
Don't listen to other reviews, these do, in fact, come with both trucks. I don't know what the other people are talking about
Despite what they tell you in the product description, they will only send you one truck. Even though it is clearly labeled as ***2*** in the name of the item.Extremely disappointing...especially considering that this was supposed to be a gift.
Answer: no
