@Frederic thanks for your help and guidance today. My mistake/lesson learnt, esp as second lead, is to stop in a safe place and wait, the moment someone in the convoy is stuck to avoid a similar situation. The sand in that area was so soft and it made recovery very challenging. Massive apologies to the rest of the convoy for holding up the progress.
Thankfully the rest of the drive was smooth...
@Nivin this time, when I got to the top of Fossil Rock, I made sure I stopped on the harder sand and pointing down. thanks for the tip.
@Lisa Pembertonthanks for the explanation today on the MM compressor. I have passed on the information to my friend. He will probably go for the MM instead of Bushranger due the price point and 5 years warranty.
