I like having a carpet on the floor of the tent. Makes it nice to put your feet down in the morning or in the middle of the night when you have to get up to pee or stoke the stove. Also makes for a nice floor under the cots to put our bags and other belongings. We have a heavy commercial carpet we use for the floor over a tarp for a moisture barrier and it isn't hard at all to keep clean , within reason. Muddy boots need to stay outside or be cleaned off before entering but we seldom hunt in heavy mud- usually dry for deer season and snow for elk season...

Never underestimate your ability to overestimate your ability.
