Because of the strong structure, which incorporates Azdel composite panels, a Tufflex PVC roof membrane, and laminated sides, any Northern Spirit XTR travel trailer by Coachmen will last for years. The panoramic front window will let in natural light and make the space feel more spacious, while the "Twice Cool" twin ducted A/C unit will keep you cool during your summer camping trips. The external dog wash and dog leash clip make each model pet friendly, and the heated and enclosed underbelly will help you extend your camping season. On all models save the 2146BHX, which offers a versatile Murphy bed instead, these travel trailers include abundant storage space, including a pass-through storage with a motion controlled light and Max Bed Storage. With the Northern Spirit XTR travel trailers, you can have a little eXTRa!
