I have an Equal-I-zer with 4 point sway control which uses friction at 4 points to address any sway issues. I do not understand how the effect of the systems are different. In other words, how can one system using friction be safe in slippery conditions, and another not? Since they both work to keep the trailer and the truck in line using the same principle, how can they be different?
I use the Husky Centerline TS (trunion/friction bars) with 1200 lb bars on a 10k trailer with 8420 lbs on the trailers axles with the wifes 1500 crew cab chevy 4wd . I use the trailer/Husky on wet pavement/gravel roads/muddy worksites (no snow or ice) and have no issues making turns going forward or backward at any angle.
Husky only comment about wet/snowy/icey/gravel roads is slow down and don't make any sudden maneuvers.
We don't know how he has his hitch setup (axle weights/measurements).
We don't know the condition of his front tires.
Or what the tread type.
or tire pressures used.
or speeds...
Rear diffs locked ?...
other criteria..
