Thank you.
I checked out the build video on the company website. It appears as they are adding some color to the interiors by using Adzel composite panels.
I laughed when the salesman says, "you can use a water hose to hose down the interior on those muddy hunting trips". My DW would think I went totally nuts it if she saw me try that.
I would imagine they would use a bit of propane to keep it warm during the winter. My experience with aluminum framework, it transfers cold. I can feel the cold studs while touching the camper walls in my heated camper.
