Recreational vehicle business A-Liner was founded by Ralph Tait in the early 1970s on the premise of selling a revolutionary A-frame pop-up trailer. Lightweight units designed to be easy to store and maintain, A Liner camping trailers offers a quick 30-second deployment time for customers. In 2009 and 2010, A Liner produced 15-foot and 18-foot travel trailers in addition to their camping trailer range.
