How to Choose the Right Trailer Size
Here are a few helpful tips to guide your choice:
Estimate Your Guest Count
Use a general rule: 1 stall per 50–75 guests for 4 hours of use.
Event Duration & Type
Multi-day events or job sites need more capacity or cleaning rotation.
Luxury vs Utility
Choose upscale interiors for weddings and special events. Go durable for work crews.
Location Access
Some venues may only accommodate smaller trailers — especially important for backyards or narrow driveways.
