Used Skyline Travel Trailer : Founded in 1951 in Elkhart, Indiana, Skyline initially produced the affordable housing units popularly known as house trailers or mobile homes. These units evolved into today's manufactured and modular housing. In 1960, we opened our first travel trailer plant. From the very beginning, Skyline continues to be committed to producing the best products at the best prices. It has earned a reputation for uncompromising integrity in all of its relationships with communities, suppliers, retailers and with the hundreds of thousands of Americans who live in Skyline-built homes and enjoy Skyline-built RVs.
