Keep convenience features clear in the proposal
If flushing or an internal sink matters, name it in the request. Ask whether it is included in the quoted equipment and how it is attended. Do not treat a category label as confirmation of every pictured feature.
Specify the upgrade you want
Deluxe is a category, not a universal specification. Some proposals may include flushing, an internal sink or other convenience features; others differ. List the features your users need and have the rental contact identify the actual model. A nicer exterior alone does not establish washing provision, lighting or accessible entry.
Compare a cabin with a trailer
A flushing portable unit and a restroom trailer are different arrangements. Review the number of people using the facilities, expected visit pattern and available approach. If considering a trailer, discuss its setup, utilities and space separately. Avoid ordering a larger category when a targeted feature would answer the actual need.
Keep supplies and service in the quote
Ask how the proposed system is replenished and attended during the rental. Explain long event hours or concentrated breaks. Confirm who receives service questions and what to do if a feature stops working. Do not add chemicals, connect unapproved utilities or modify the unit to imitate an advertised feature.
