We bought our first camper this summer - a 2002 Coleman Fairlake. I did some renovations to it (replaced wood, flooring, paint, curtains) and have been getting it prepped for our second trip. Our first trip was in September and it was just 2 nights and it was hot. This trip is Thanksgiving week for 6 days in the Gatlinburg, TN area. We are expecting it to be cold and possibly snowy. The unit has a Coleman Mach 3+ with a heater module that seems to warm ok, but certainly doesn't make it toasty inside even when it's warm outside. I also have a small ceramic space heater, electric blanket and the standard PopupGizmos (haven't tried them out yet) and 3 children under 5. We live in Texas and aren't used to colder weather preparations, especially with a camper. I just wanted to see if there's anything we are missing or should consider before we leave.
