## Overview

The Gulf Stream Trailmaster Lite Ultra-Lite 257RB puts the bathroom at the rear where it has room to breathe, with a neo-angle glass-door shower and a skylight overhead. Up front, a Queen bed with strut-assisted lift pairs with craft-made hardwood cabinetry and an Everchill refrigerator. The Lite Value Package adds some genuinely useful touches, including a tankless water heater, power hitch jack, electric awning with LED lighting, and radiant LED interior lighting throughout. An optional half outside kitchen rounds out the package for those who like to cook and entertain at the site.
