Mike,
As noted, many fans of both. We'd already made our decision, but took a Northwood factory tour and saw the Arctic Fox 990 in various stages of completion. We we're very imperssed with the attention to detail, QA process and the details of the employees incentive pay as how it related to zero defects. IMHO, it would be well worth the half day drive to La Grande,Or to see how they're put together. If you're able, I believe Lance in Lancaster, Ca also offers tours. There should be plenty of AF owners in your neck of the woods to solicit first hand feedback at local campgrounds. We've only had ours for a couple of weeks and have given a few "tours"already!
