I've got this L desk I just replaced. Each of the two main pieces are 5 ft long, so its a little spacious but really nice of for holding a computer and craft space. Screws together at the center point and I keep it as two pieces movability. 

Could easily fit in a van or truck, but could manage a smaller car if broken doen more. Has  a few extra pieces I didnt know what to do with as I got it secondhand myself.
