2019 Forest River Flagstaff 29RKWS, Flagstaff travel trailers are built and backed by Forest River RV which is a division of the Berkshire Hathaway Company. Flagstaff RVs are one of the most durable light weight trailers on the market because the trailers are vacuum bonded on all six sides. The floor, walls, roof, fronts, and backs, are all vacuum bonded to make sure your trailer is light weight and built to last. Structurally engineered materials make the walls some of the strongest in the industry. See the Flagstaff travel trailers for sale at Ron Hoover RV & Marine.
