Hi Paul welcome to the forum. can you give us a bit more information of the needs so we can hopefully provide better advice?
For instance. Does it have to be a 5th wheel or can it be a travel trailer or a mobile housing unit?
Are you saying you are envisioning needing to purchase 25-36 units every year?
Are these units going to be mostly stationary or are the users going to be moving them from time to time.
Based on what you have provided I would reach out to some of the major manufacturers, describe what you need and see what they can do to help. Most of the big manufacturers have in the past provided FEMA trailers to municipalities to house people after major disasters. These trailers typically are towed on site and hooked up to municipal services for water and power Have a household refrigerator and have a regular flush toilet.
Whereas a standard RV, travel trailer or 5th wheel have special toilets that flush into a holding tank where the sewage sits until the tank is full. Then somebody has to manually do something to get rid of the waste.
