Re: Cyclone underbelly ?.
Hi NevadaNick,
Welcome to the Heartland Owners Forum. You'll find a lot of useful information here along with a bunch of friendly and helpful people.
The Canadian Arctic Package includes tank heating pads (110V) to keep the water tanks from freezing, heat tape (12V) on the fresh water line to the pump, and additional insulation. I've attached a graphic that explains.
My own experience is with a Landmark in subzero weather (F). We have tank heating pads and heat tape on the fresh water line, but don't have all the additional insulation provided by the Arctic Package. Nevertheless, we do fine. We do have the electric fireplace in the rear of the coach however, and we hang lights over the water pump and in the UDC. We also use a heated water hose. I've also added heat tape on the water lines to bathroom and kitchen to keep them working when temps drop below -15 F.
I'd expect Cyclone owners will chime in with any other relevant info.
Btw, duplicate posts are not permitted so I've deleted the other post.
