What drives the price difference between a weekend and a monthly rental?

The gap comes from how delivery, pickup, and route time get spread across the days you keep the unit, not from a different toilet.

A weekend standard unit still burns a full delivery trip and a full pickup trip. Those runs land on the busiest days of the week, when drivers are already juggling party and event drops. The unit only sits in inventory for a couple of days, so the company has to cover that truck time and the empty slot in a short window.

A monthly job folds into a standing service route. The same truck already in the area pumps the holding tank on a set day, so the per-day truck cost drops. Delivery happens once at the start and pickup once at the end, then the unit earns its keep for weeks instead of a weekend.

Short event rentals also carry more tip-over and late-night mess risk, plus same-day pickup requests. Long construction or home jobs are quieter and more predictable, which is why the monthly line looks cheaper when you divide it by the week.

Ask them to break out delivery, weekly service visit, and the rental line on the quote. That shows where the weekend premium is coming from without comparing apples to oranges.
