I’ve had the Oz Glide hitch for 2 and a half years, during which time I’ve done over 3,500k’s of dirt road, many corrugated and rough – including the Gibb RR this year (in our 3.5 ton off road van).
The hitch performed flawlessly; the ride it gives to both vehicle and van is very smooth. You almost forget you have the van on the back!
The contents of our van seem to have a much smoother ride, especially after talking to others on the GRR, we escaped without damage and they weren’t so lucky!
I can’t recommend the Oz Glide highly enough. In fact, 3 of us who travel together all have them in the same caravan park just now, with 2 different handbrake setups.
