I've spent plenty of nights keeping the rain off my face with a dirty forearm before buying a tent. DW had a penchant for wanting to leave on a long weekend camping trip right after I got off work, so I have set up the tent many times at midnight in the rain with a flashlight clamped under my elbow. In DW's latter years we moved to a 5er and private campgrounds so she could have her oxygen collector plugged in all night. Now, while I love taking the 5er out, my youngest son and I will load a tent and sleeping bags to pull an ATV and dirtbike into the high country. I have given up sleeping on the rocks altogether though. We set the tent up on the utility trailer for the night.
