Is this the one you're looking at?
Wildwood FSX 180RTIt does look like most of the weight of the ATV would be behind the axle. As least most of the other storage is in front of the axle including the under bed storage and kitchen stuff. I like the size of the tanks on this one, not bad for a small TH.
I'd get a WDH with sway control and be on my way.
A few years ago I looked at the Cherokee Wolf Pup in the same floor plan and really liked it, it had a wet bath instead of a dry bath like the Wildwood.
You can look on manufacturer specific forums for people with the same model and see how they do towing.
