Does anyone know if the Rogue is certified for towing four down behind an RV?

Acoording to the owners manual, you cannot flat tow the Rogue. You must use a tow dolly under the front wheels (2wd models) or flat bed trailer for AWD models.

Reason: The oil pump in the transmission will not operate when towed and the lack of lubrication will cause transmission failure. This is not just just an issue with CVT's or the Rogue. Most vehicles equipped with automatic transmissions have similar warnings or put limits on towing distance and speed.
