A Caldwell delivery covers about 28 miles of I-84 from Boise, so book early for weekend events. Gravel winery lots and farm yards are fine when firm. The truck must reach level ground within about 30 feet. Soft, freshly watered lawns can block a heavy restroom trailer.
Restroom trailers need a level spot and a 110-volt, 20-amp outlet or generator. They also need a hose hookup or onboard tank. Check that before you sign a venue contract.
A 150-guest, 5-hour Caldwell wedding with a bar needs 5 units by our method. That is 150 divided by 40, rounded up to 4, plus 1 for alcohol. Make 1 of the 5 an ADA unit, and add 1 hand-wash station when food is served.
| Caldwell example | Units |
|---|---|
| 80 guests, 3 hours, no bar | 2 standard |
| 150 guests, 5 hours, with bar | 4 standard plus 1 ADA, 1 hand-wash |
| Crew of 35 on a home site | 1 seat and 1 urinal per 40 workers (OSHA) |
