oh, it is kit, it comes in a 4x8x about 2 foot tall package. there isn't much for grade either way. It will be freeway, I can stay in the slow lane early on a weekend which is how I usually do it with the truck. But the trailer idea kind of appeals to me. All except for the 6 volt part, there would be no trailer braking available, or lights. Maybe I will load it up and drive around the neighborhood a bit to get an idea.
