Cot for sleeping for sure. Whatever pad set up is comfy and warm. The nice thing about using a cot is the extra storage created under the cot. We use Rubbermaid totes for gear and these fit under our Cabela's XXL Guide series cots perfectly. For lighting the last few years its been led rope lights from Menard's powered by either a deep cycle battery or a Schumacher power box. Just running the lights in the morning and evening we easily get over a week on the power cell without charging. Regarding heat, yes a Buddy heater will work ok but after a few days you will notice things starting to feel a little damp. Wood heat is great but I had a hard time cutting a hole in my new tent for a stove jack. We ended up switching to Chinese diesel heaters for both Kodiak tents and ice fishing houses. They are relatively cheap, have been bomb proof so far, and consume very little diesel fuel. It's basically like having a forced air furnace in your house. Just google" Chinese diesel heater" and there is more than enough info out there. For all the non-USA haters, you can get the original german made heater but all in, it will probably cost you 5 to 10 times MORE money. We went the cheap route to test the water and so far have been nothing but happy. But....to each his own. The Kodiak tents have served us very well. In my group we have three 10x14's and a 12x12. All great tents with 10-30 days per year and oldest one is about 7 years old. Another small tidbit would be the Stormfly now offered by Springbar which is the original company that made that style tent. The Stormfly offers even more protection from UV, rain, and snow but an added benefit is the additional stability in nasty wind. We mainly hunt in western ND, MT, Wyoming, MN and have been out in some VERY windy conditions. Highly recommend the Stormfly. Fits the Kodiak tents perfectly. Enjoy your upcoming hunts!
