## Overview

The Gulf Stream Kingsport Lite Ultra-Lite 257RB makes good use of its single slide by tucking both the jack-knife sofa and dinette inside it, opening up the main living area considerably when you're set up at camp. The rear bath is a genuine full bath, complete with a neo-angle shower with a glass door and a skylight over the tub. A Queen bed anchors the sleeping end, and pass-thru exterior storage gives you a practical place to stow gear without eating into interior space. The one-piece synthetic vinyl roof carries a 12-year supplier warranty, and Gulf Stream bonds insulation directly to the walls to prevent settling over time.
