2 adults 2 teenagers in 28' Class A for a week?

We're going to be in Tomaka in Florida. We don't use the shower and are number one only toilet use. I've got a 5 man tent and two chairs I can put inside, as well as a window AC in one of the doors. They can use that to dress in. We'llbring an extra tv and antenna in case they or me want to use it as a living area.
