I have a large camouflage tarp I use a lot. It keeps the tent and everything else dry. When it rains and I'm wanting to setup or break camp, I can do that without my tent getting wet.

I usually just run a line under the tarp and tie each end of the line to a tree. I now have 2 discs that go onto the line and sit near the tarp to prevent water from running along the line and into the area I'm keeping dry.


Cheers
