SetPower Insulated Protective Cover for RV45D and RV60D Insulated Transit Bag 12 Volt Portable Refrigerator Cover

Seems to helpful with cooling efficiency.

First, Setpower customer service is excellent. The cover is high quality and fits well. I have not tested this camping yet but so far so good. The price at time of this writing is $90 + tax so I am not sure if it is worth it for the insulation benefits. I have yet to test out the difference. Overall, nice fitted cover.
