Hello, My family is looking to purchase a lightweight travel trailer to be pulled behind a 2004 Ford Expedition equipped with the 5.4L and trailer tow package. We are looking closely at the Flagstaff 27BHSS. I am interested to hear about your experience with a Flagstaff model TT. I am also curious about the differences between a vinyl vs rubber roofs as the Flagstaff is fitted with a vinyl roof. Questions and comments would be appreciated. Thank you!
