Is a hot tent needed for second season rifle Colorado?

Right now i'm trying to decide between 3 options:

1 - A jeep/truck with a roof tent which has a propane heater. My concerns with this option is, no real standing room in the tent although the vehicle will have an awning which is nice for cover, although that part obviously won't be heated. Also if we get crushed with a random snowstorm, not sure how well the roof tent holds up in that situation.
2 - Rent a canvas tent with stove and cots; probably the best overall option comfort wise, but lots of work to put up and not a lot of flexibility if we want to move to a different area.
3 - Get a hot tent and go that route; kind of somewhere between the first 2 in terms of comfort and flexibility/ease of setup.

FWIW there will be 2 hunters and we will be around 8500-9000 feet

The last few years on 2nd/3rd season hunts, I've been using a 10x14 Kodiak Flex-bow and it has been awesome. Way faster setup and tear down than a traditional canvas wall tent, and plenty of room for two guys. Comfy cots, you can stand up, and just run a buddy heater on a 20 lb propane tank or two. Just make sure to crack a window to vent if using overnight. I also pack a CO detector for peace of mind.
