It was Franco (I believe on another site) who demonstrated that with string, masking tape and careful attention to the specs on the website, you can duplicate the space of any tent.

Of course, if you set up the tent indoors (masking tape and furniture will help you), you can determine this in time to send it back if it doesn't work. You'll be out only the shipping cost.
