That’s exactly what I do. But my otter pro shack holds warmth great. And I couldn’t say the most important thing is a good sleeping bag. Not a cheap one or you will freeze. We camp on the ice in portables all the time. I’m doing it on red this upcoming weekend. I dont use any thing one the floor. I use the sled as my dry area.
bearcat, which sled are you running? I have a Pro Cabin X-Over and would love to run a cot inside of it, however most cheaper small cots are too short to clear the tub and most “big” cots are too long to fit in the shack. I saw a youtuber with a cot, head area in the tub feet area in the fishing zone, I asked him which cot he’s running but got no response.
I camp in my hub shack, but would love to use my otter cabin due to better insulation and having the sled.
