## Overview

The MDC USA XT15-4E Base is built around a go-anywhere premise, with X-TRACK independent coil spring suspension, heavy-duty shock absorbers, a Cruisemaster DO35 hitch, and 265/75R16 MT tires on aluminum alloy wheels with two spares included. Inside, an Olympic Queen bed sits alongside twin XL bunks, sleeping four without a slide. The cold weather package is genuinely comprehensive, covering heated water tank pads, a Truma AquaGo anti-freeze kit, a self-heating Renogy REGO battery, insulated lines, and a Truma VarioHeat furnace, so cold-weather camping is a real option rather than an afterthought. Two separate three-burner cooktops, one inside and one on a slide-out stainless steel body outside, plus dual 31-gallon fresh water tanks and a full annex with enclosed floor and draft skirt, give the MDC USA XT15-4E Base a level of self-sufficiency that punches well above its compact footprint.
