The Heartland Gateway 3400SE is built around a residential-minded interior, with English maple cabinetry, solid wood cabinet doors, stainless steel undermounted sink, and solid surface countertops throughout. The bedroom delivers a Queen pillow top memory foam mattress, under-bed storage, a walk-in wardrobe, and a washer/dryer closet, while the oversize shower with glass door and porcelain toilet round out the single full bath. Outside, the Gateway 3400SE rides on Dexter axles with Mor/Ryde suspension for confident towing, and the full pass-through storage bay with tie-downs adds serious hauling versatility. Optional upgrades like a King bed, 6-point hydraulic leveling, dual pane windows, and a 12 cu ft GE refrigerator let buyers tailor the rig to their priorities.
