I want to purchase a winter tent while they are on sale. I live in Florida. I own a Kelty Gunnison 2.1. I seem to only get the time to go camping on the coldest days of the year in FL. The temps are usually between 25-40 degrees. I am always cold. I am looking for a winter tent that will keep me warm (and my 3 year old son). I plan to use it only in FL and Georgia so I dont need huge snow protection. Can anyone tell me a tent that seems to keep the inside warmer? Thanks, Dennis
