The transport ship that Luke Skywalker boarded when he went back to Tatooine in search of blockade runners for the Rebellion was a vessel with a circular design, able to carry a X-34 landspeeder. Sadly, even with a camouflage tarp placed on top, the Jawas ended up claiming it as salvage.
Even though the ship is only seen briefly in the narrative, it has a potential resemblance to a YT-1300 light freighter.
