It all comes down to your requirement – if the need of the hour is to shield the car from the sun, rain then a tent is better. However, the shield is mostly for dust and water. So, it all depends on the buyers. A tent is also more expensive than a cover. It is easy to find a cover anywhere; however, for a tent, you might have to do some more digging. Thus, making sure you have an open space that is large enough to accommodate the canvas is the second important factor to consider here.
