## Overview

What sets the 354FLS apart is how the front-living layout puts the entertainment center. Heat and massage theater seats, a 50" HD smart TV, and an automotive windshield. Right at the heart of the coach, making it feel more like a Class A lounge than a typical fifth wheel. The kitchen earns its keep with solid surface countertops, a Furrion 3-burner cooktop with oven drawer, a residential 30" microwave, and two pull-out trash cans that actually keep things tidy. Two entry doors mean the front and rear ends of the rig each have their own access point, which is a genuine convenience once you're set up at a site. Towing hardware is taken seriously here too. Lippert axles with ABS, H-rated 16-ply tires, and the Road Armor shock-absorbing pin box make for a more confident haul on the highway.
