Hi,
As my Cub Escape wheels track is wider than my challenger wheel track by approx 100mm in each side of the Challenger wheel track.
I decided 2 x sets (4) MaxTraks would be the safer way to go if we got stuck in the sand with the Cub attached.
As yet they have not touched the sand, I had no problems at all on the recent Fraser Island MySwag trip on Fraser Island.
BUT there is a VERY soft patch of sand on Inskip point, the last 100m before you were on hard ground, The challenger was working hard to get through, and we only just made it.
