Cross-Country RV Adventure

Breana Evans and Robert Haley love a great adventure. They're moving from Boise, Idaho, into their RV full-time so they can live a more intrepid lifestyle. Ideally, they want a lightweight unit so they can pull it with their current truck. They also would love as many windows as possible to guarantee the ability to see all the sights around them as they travel. Which unit will they end up driving away with?
