As the grandkids multiplied and grew, our FC23FB became smaller. It's still our preferred size for our travel adventures, though. We've tried various extra sleeping accommodations for 2 grandkids at a time, and this one appears to be our solution. This Bigfoot rooftop tent is very well constructed and comfortable, and collapses in the fiberglass shell to a very slim aerodynamic package. Two minutes up, two minutes down and ready to roll. Ladder and sleeping bags ride inside the shell. Three little girls along on this trip, having a great time!
