The barrels inside the car tents, when opened, fill with water when it rains.
You can empty it, but the objects in it don't always dry out. The leather sewing kit has dried after a few hours, the boots are still damp. Many other objects are still wet.
At least the car awning would need to be repaired, because it should protect everything contained certainly from the rain and, often, we also works with the rain and you have to leave the barrels open for this... and it is neither right nor logical that, even under to a tent, fill with water.
