Some might want to know what kind of pad and/or sleeping bag you have. I have heard you can paint on to the pad a silicone or silicone/paint thinner solution. ? The last I used, I had to apply powder to dry the paint thinner, it wouldn't dry out completely on its own. Newer formulation I guess. I put a grid on the floor of my BD Hilight to keep the pad from sliding around before I even used the tent. I have never had a problem, but had heard that silnylon is slick. I do tend to move down on the pad if camped on a slight incline, I roll from side to side consciously most of the night.
