## Overview

This truck camper transforms with three slides that dramatically expand the living space - a 7-foot kitchen slide, 5-foot rear slide with jackknife couch, and 6-foot side dining slide with convertible benches. The kitchen impresses with an 8-cubic-foot 12-volt refrigerator, convection microwave with air fryer, and a kitchen island featuring a 24-inch apron sink and built-in spice rack. Built for serious off-grid adventures, it comes equipped with a 314 AH lithium battery, solar prep wiring, and a heated basement with generous tank capacities including an 80-gallon fresh water tank.
