I saw the brochure description, I just wasn't sure how cold the heated underbelly could endure
I read on another site in order too keep the black/grey valves from freezing to pour enough antifreeze down them to cover the bottom portion of the pipe that is beneath the shrouding.
I did a lot of winter camping in my younger years (tents and snow caves), now that I am older (and not as broke) I would still like to go winter camping, but in comfort!
I sure don't plan on being out there when it is -40F, but if it gets to 0F I am hoping that I don't run into any issues.
Thanks again for all of the insight.
