I use a couple of IKEA SKUBB collapsible boxes. I can hang it from a carabiner or bring it into the tent. They collapse down flat and leave them in the tent when it gets folded up.

Very cool - thanks for sharing that!
The Rubbermaid bin I use is the 10 gallon size Roughneck

Is also great for a wet awning and the mat. Last rainy trip, we got everything put away, then rather than trying to stuff the wet tarp into its stuff sack while standing in the rain, we just put the mat in the bin, followed by the tarp. Poles went in the stuff sack. Put the lid on, and then there is very little "wet stuff" smell inside the van.
Sometimes, if it a grassy site, I just put a tarp under the van and then shoes, folded camp chairs, speedmitton stuff, etc, are under the cover of the van, sitting on the tarp. After the rain, or in the morning (dew), you can drag the tarp out with all the stuff rather easily.
Finally, A good additional raincoat, or poncho AND
rain paints were invaluable when tent camping with the family. After every item was packed, I sent the family into the car and took down the wet tent in protective clothing so everyone else could stay dry. Often, we would hit the bathroom on the way out, and I would bag these soaking items and change into dryer less severe gear for the trip to the restaurant for breakfast - LOL! Hey, it was raining with two sub 5-year-olds on out month-long trip!
