The Heartland North Trail TT has a slightly different looking axle, they call it the WIDE-TRAX Axle. A little more spread, and I think lighter duty looking. Any experience or insight on this set up? ...
I have them on my Wilderness. It does make it more stable during highway driving. You do not get the same amount of bounce. Towing in the wind is better as with the passing of trucks. A slight negative is in very tight turns, you do get a little more tire scrubbing than the standard spacing. Since 99% of your driving is highway, I see this as not being a issue.
