Arctic Pac

[Marlena]

We recently purchased our first RV. 2004 Forest River Sunseeker Class C. We need info on the Artic PAC. What exactly is it, how does it work and when and if we should be using it???

Welcome to the forum its a great place to get your questions answered. The Arctic Pac can mean different things on the same type of rig depending on the year of Mfg. Basically it is maybe underfloor insulation and tank heaters. Normally tank heaters are not turned on until the temps are really low for an extended time and then only if you have liquid in the tank.

Arctic pack is just 12V tank heaters on the back and gray tanks.

Here is some info. This covers everything...but what you have is just a pad on the black and gray tanks.
