I'm going camping with my family and grandsons in a couple of weeks. I'm debating if I'm going to need to use heat. This wouldn't even be an issue if I didn't have little ones with me. Both my grandsons are FL born and used to being warm. They are 2.5 and 3 years old. The night time lows where we will be are going to be in the mid 60's. It may sound warm, but then I was thinking how chilly it feels in the house when the AC is lower than 78. It could be a full 15 degrees colder than that. I know I'm over stressing about it. It's been so many years since I've camped with my own little ones and had to worry about temperatures. I'm going to test out my pup furnace and check all my lines and I'm deciding if I need to also buy an electric unit. So at what temps do you feel you need heat, especially with little ones?
