Hi Martin well done man your rig looks fantastic and I like the braai grid always around in the pictures.... Is it not wonderful not to have to worry about sand, mud etc anymore as the sidecar platform is so stable with the third wheel?
You can fit a steering damper to the front of your rig to help with the head shake in the sand if it bothers you that much, I don't want one on my rig as I find that if you are aware of it and hold on it's fine. The steering damper (old VW kind) tends to make the steering under normal conditions a bit harder and I do not like that...
Many happy miles and i fyou are ever in SA please pop past...
