Define ''All Season'' campers please

We never felt any draftiness or cold floor in ours. I did put in our carpet for this last trip. I got up in the middle of the night for my trip to the potty and was in just my shorts (not a good picture but I keep the lights off) and bare feet, I did not feel that cold on the floor. At night I never ran the electric just the furnace, it would cycle on about every 20 to 25 minutes for about a total of 5 minutes. The fan always comes on first and then it runs after the gas shuts off so I figure the actual gas was on for the furnace about 4 minutes each time. I now know that we could have lasted on our one tank of fuel for the entire trip.
