I had a toilet installed in my tent. A North Face tent, with the four crossing aluminum flexible rods. Those used on Mount Everest. Imagine that. I purchased it in the early 1970ís to use when collecting Fossil Vertebrates on Ranches in western Nebraska.
Climbers on Mount Everest used their North Face as a toilet as well. It is cold at elevation. Body parts can easily freeze if exposed to fridgid wind. Also during daylight hours. The toilet worked very well, if promptly used.
I used a flashlight in and out of the tent for light. Open the tent vents for fresh air.
A Shower was added to the North Face Tent. A one person shower with only cold water. It drained into the toilet. The Tent was Level. No gauges. If it was full. I knew. I had to squat to fit when washing my hair in the shower.
A card board box with clothing served as my dresser. A carton of food, some geologic maps tucked in between the toilet and shower. This was great insulation, also.
The sleeping bag rested upon a inflatable mattress, but uncomfortable. I found a Memory Foam mattress, cut it down to size to fit the open space available. It was very comfortable.
A folding chair sat outside the tent with a small plastic folding table. A propane cylinder cooktop sat on the tailgate of the small 1978 Toyota 4x4 with camper shell. This was before Toyota offered full sized trucks. This was a four cylinder. Great gas mileage.
I had a fork, spoon, a butter knife and a hunting knife attached to my pantís belt. I ate food out of a can if the contents did not need heat. Otherwise I used a stainless bowl that was purchased at a Laramie, Wyoming garage sale. Also several sweaters and a hat.
The five gallon water jug lasted a week to ten days. A water system was extended from the Black Hills of South Dakota across a pasture at this Ranch and kept going, somewhere. I did not follow it to the end. There was a pump head where I lifted it and cold fresh water was available in the Badlands at 100 degrees on cooler days. I could also use this to wash up, if needed.
When I passed my 29th Birthday... I felt no longer immortal. Passing 40 years of age was tough with a wife and two daughters. Daughters slept in the back of the Toyota Tundra. I had upsized the vehicle. Kept the North Face Tent. The tent is rolled up in the carrying bag in the garage. A bit small for todayís standards.
As 50 went by I said Hell with the Tent, the toilet, the shower and the cardboard boxes. At 56 years old... I bought a 2006 23 foot Safari with Solar. It was nice. The Airstream had everything the tent had as standard.
I currently have a 2019 27 foot International. It is OK. I set the North Face Tent next to it. The tent has a toilet and a shower. I use the International to store things. Life is good.
