Camped with the fireplace.
It was showing 29F on the dash when we turned the truck off at midnight.
Camper was around 70F in an hour or so. (Lowish setting and no Fan - Fan wasn't wired up in time)
Agreed on the ambiance... There is something special about having a flickering flame.
If you are gonna camp in some really frigid temps, but want the flickering flame, I would recommend a buddy heater to take the chill out of the camper and get things up to temp, and the Dickinson can run all night.
I have some plans to add some insulation to the camper. Keep in mind, this is a giant aluminum box, and aluminum is really good at being effing freezing when it's freezing out. Additionally, the water tank has become just about the coldest thing in the camper (You will never get the back wall warm once 13 gallons of water is cold). You can feel the cold radiating from the water tank.
If the water tank wasn't such a pain to install/remove, I would prob throw some insulation behind it. I have some plans to add some to the front of the tank.
I am guessing it was in the mid to low 20s that night and the Dickinson with no fan did a really good job of keeping us comfortable. I wasn't hot, but I was in a -30 Coleman extra large sleeping bag, with no extra blankets, in shorts and a tshirt, with no socks... I woke up a few times and saw the light flickering... I was pretty happy.
The gravity feed on the water tank has frozen up on me 3 times now. It typically defrosts fairly quickly, but it is something that I would like to solve for. (This happened with the Dickinson on as well) It may be worth wrapping the line in something, but I highly doubt that will work. The best solution may be to drain the line before going to sleep.
We also added a full size Roof Rack from Sherpa
https://sherpaequipmentco.com/shop. It fit incredibly and really made a different in how the truck looks. The maxtrax fit awesome in front of it and the GNARLY wind noise I had is completely gone. I really want to see if I can squeeze the table in now.
