Wow. Thanks for all your effort. I haven't been able to find the exact model of this van as there seems to be various variations of this model. The 2011 Nissan Caravan Van is a member of the model’s E25 (2001–2012) generation, and the two model codes I do have are like mine, with are low tops roofs are LDF-VWE25 and CBF-VR2E26. After 2012 is the NV350. Unfortunately the Caravan model isn't within that list either.
