2016 Jayco Greyhawk(31FS)

As a group, I'm not sure where you are going, but you will likely find it easier and more comfortable, along with cheaper to rent a passenger van and a cottage or house with multiple bedrooms at your destination. 10 adults in a total of 240 sqft is going to be very tight, One or two loud snorers, humidity from 10 bodies breathing in a tight space, etc will be more familar than most groups of 10 want to be.
