Manduca sexta
Found in my garden on a tomato plant, after notices chewed leaves, fruit, and feces on the leaves. Larva of Carolina Sphinx Moth
Yeah i guessed I never bothered to compare the two, just made an assumption because it was on my tomato plant.
Though similar, Manduca quinquemaculata has eight v-shaped stripes rather than seven diagonal stripes as your caterpillar has here. http://bugguide.net/node/view/5011
