My trailer is from Nash's other company, ORV. Both use the AF/Nash chassis.
It does great off-road. I mean actually off-road, not just off-pavement.
I did rip off the rear stabilizer jacks. I replaced them with power jacks, but relocated them about halfway between the rear axle and rear bumper. I added some mini steel rollers instead. It does get drug through dips, but even completely off-loading the axles doesn't seem to even really flex the trailer (it does make the entry door bind slightly but it still opens and closes). I've even had to to winch the whole combination up about a 1-1 dirt slope, after the trailer slid off the edge of trail.
The sidewalls do scratch when dragging it through the tress. They come out pretty easy though. I do recommend fully encased slide toppers of you add them, because tree limbs can be rough on the fabric. Ditto the awning.
The one downside of an Arctic Fox is weight. Even a 22' might push the limits of some half-tons. Also consider that some trails might require disconnecting the WD bars, so your receiver needs to be able to support full hitch weight w/out weight distribution. A Wrangler would have no chance at towing an A/F.
