## Overview

Owners consistently praise this Forest River Cardinal 3640 for its home-like livability, and the residential touches back that up: glazed cherry cabinets with crown molding, La-Z-Boy swivel recliners, and a 40" HD TV on an electric lift in the living area. The bedroom is a genuine retreat with a 72" x 80" Serta innerspring King mattress, a cedar-lined closet, under-bed storage, and even a built-in safe. A drop-frame pass-through storage compartment handles the gear, and options like a fireplace, stack washer and dryer, and a convection microwave push it further toward full-time comfort. As with the broader Cardinal line, a careful pre-purchase inspection is worth the time to check fit and finish.
