Back numerous years ago I had a lady who enjoyed to go camping, she was from a small city plus a completely different lifestyle than me. I was from the city plus was not into camping in the slightest. However she talked me into going with her. She had a camper so if I couldn’t deal with sleeping in the wilderness I could retreat to the camper for the evening. So the people I was with and I went, plus let me tell you that I absolutely didn’t mind the whole experience too much. But when it got to be evening time I had to go in the camper. It was way too cold out for me plus the camper had a wonderful oil furnace in it. Actually there was a space oil furnace plus then the proper gas furnace. The gas furnace in the camper was able to be ran without having to start up the engine. I don’t think how exactly that worked, but that was the case. I have to say though that I will not go camping again. Although I didn’t mind it in the day I truly need heating or air conditioner wherever I am at! Out in the wilderness there is no way to have any heating or air conditioner obviously. And unless it was the perfect temperatures in the area the people I was with and I would be camping at, it would need to be heating plus air conditioner for me all the way! My lady thought I was rather silly with my need for heating plus air conditioner.
