Class A motorhome: water & holding-tank capacity for Burning Man
| Fresh water | 90 gal |
|---|---|
| Gray tank | 55 gal |
| Black tank | 45 gal |
| Shore power | 50 amp |
With a 55-gallon gray tank and a 45-gallon black tank, the Class A motorhome is set up for self-contained camping. Gray almost always fills first at Burning Man because showers and sinks generate the most water, so a crew of two or three can expect a pump-out roughly every 4–5 days.
Its 90-gallon fresh tank covers about 5–6 days for that crew before you’ll want a water delivery or refill, since fresh use tracks gray plus black output. These are rough averages — plug the Class A motorhome into the planner for exact pump-out and refill dates based on your dates, crew, and shower habits.
