My girlfriend and I have been getting everything together and are almost ready to leave for the van life. I was born in Southwest Florida and have been in the same town for my entire life. Its recently occured to me that I don't know how to fare with the cold and will need some advice on sleeping in the van up north. IDK how to stay warm or how to tell when it's too cold. I've heard cars can have troubles in the cold but don't know what you have to do to circumvent those problems or how to handle them. I think the cold is going to be my largest hurdle because I've never had to deal with it before and I would really love some advice.
