so a friend of mine was gifted an Expedition, (bottom entry), and he wants to try winter camping a bit. I don't know much about HH systems so i'm hear to get the info from the HH wise ones. He's looking for the easiest and cheapest way to get into the high 20's, low 30's. I know he doesn't want to spend $$ for the super shelter etc. I suggested just throwing a couple of ccf pads inside but honestly don't know how well that works for HH .
