From its sleek fiberglass exterior to its residential-style interiors, this model combines high-end design with practical functionality.

The gourmet kitchen comes fully equipped with stainless-steel appliances, solid-surface countertops, a large pantry, and a freestanding dinette for enjoying home-cooked meals in comfort. Large windows throughout flood the interior with natural light, enhancing the open, airy feel of the coach.

The LaCrosse 3399SE also offers a private, king-sized master suite with plenty of storage and a spacious bathroom complete with a residential shower and linen cabinet. Built with Forest River’s superior craftsmanship, this travel trailer is both durable and stylish, ready to deliver years of memorable adventures. Whether you’re hosting friends at the campsite or settling in for a peaceful weekend getaway, the 2021 LaCrosse 3399SE offers the perfect combination of elegance, comfort, and performance.
