Selecting sites by rig length

Q: How can we tell whether we have a site available which will accommodate the callers rig when we receive a phone inquiry?

A: When you're making a reservation, fill in the Rig Size (down in the customer information area).  Assuming you have the "Use Preferences" box checked, it will then only show sites that will accommodate that size, according to the "Max Rig Length" attribute in your Sites setup (in Site Details, click More Site Attributes to set the max rig length).
