Hunting cabin without plumbing until spring 2027: one porta potty enough?
I run a hunting cabin in the Montana mountains with no septic system, and the plumbing install is delayed until spring 2027. The cabin gets used by up to four people on weekends from October through April, with no alcohol or heavy meals, just coffee and snacks. The ground is snow-covered and uneven, but I can clear a spot for a unit. A vacuum truck can access the site, but it's a 40-mile drive for the rental company. I'm considering a single standard portable toilet for winter use. Will one unit handle four people over a weekend without overflowing? How do I prevent the holding tank from freezing in sub-zero temps?
