## Overview

The XT16HR Island Base is built around a simple idea: go farther and stay longer. Twin 21-gallon fresh water tanks, 800Ah of Renogy REGO lithium iron phosphate batteries with self-heating capability, and a dedicated cold weather pack. Heated tank pads, insulated lines, a Truma AquaGo instant hot water system with anti-freeze kit. Mean this rig is ready when conditions aren't. The kitchen situation is genuinely unusual: there's a full 3-burner Thetford cooktop inside and a matching slide-out 3-burner setup outside, both with glass lids and plumbed hot and cold water, so you're not choosing between cooking indoors or out. A Queen bed on a pillow-top innerspring mattress anchors the sleeping end, and the full bathroom with a Thetford cassette toilet and separate shower keeps things civilized well off the grid. X-Track independent coil spring suspension, Cruisemaster DO35 hitch, and Tuson electronic stability control round out the mechanical side for buyers who actually use the off-road credentials.
