We've got the lighter version the Fox Mountain. As said very sturdy, but not perfect. We've had a few issues. Although in the realm of the RV issue world it's about average. IMO anyone who buys one and has no problems is lucky and should buy a lottery ticket every time they use it. We bought a Northwood product for a couple reasons, one they build their own frames, they don't use Lippert axles and they are close (300 miles) to us. Overall fit and finish is exc. It's the little things like any RV has that are nagging. A squeak here, a water leak there. Nothing major at all. Just little annoyances. Would I buy one again. Absolutely. Too many positive's, like LED lighting, remote control Fantastic fan, great CCC, nice fit and finish on cabinetry.
Arctic Fox are even nicer.
