Hunting camp used weekends only: monthly service or per-use?
We run a hunting camp on our ranch, used weekends only from September through November. The crew is 10 people, no alcohol, just coffee and sandwiches. We have one standard portable toilet placed on gravel near the cabin. The vacuum truck can drive right up to it. The rental company offers monthly service or per-service visits. With low use, the unit doesn't fill up fast, but I worry about odor between uses. Is monthly service enough for weekend-only use, or should I schedule service only after a certain number of user days? What's the cost trade-off?
